I am currently new to robot framework.I am currently using latest window version of chrome and chromedriver which is 80 but when i try to run the test it gives the message "SessionNotCreatedException: Message: session not created: This version of ChromeDriver only supports Chrome version 81" in pycharm but currently beta version of 81 is only available. I have tried uninstalling everthing and reinstalling it again but nothing works can anyone help me with this.Thank you!
Screenshots below:
I solved these kinds of problems using the webdrive manager.
You can automatically use the correct chromedriver by using the webdrive-manager.
Install the webdrive-manager:
pip install webdriver-manager
Then use the driver in python as follows
from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
driver = webdriver.Chrome(ChromeDriverManager().install())
This answer is taken from https://stackoverflow.com/a/52878725
Do below steps :
Check the version of chrome browser.
download chromedriver of same version from https://sites.google.com/chromium.org/driver/home
Give correct path in the pycharm and run the code.
I got the same message on MacOS:
"selenium.common.exceptions.SessionNotCreatedException: Message:
session not created: This version of ChromeDriver only supports Chrome
version 81"
Then I run this command, it's gone:
# Homebrew 3
brew upgrade chromedriver
# Homebrew < 3
brew cask upgrade chromedriver
This error message...
SessionNotCreatedException: Message: session not created: This version of ChromeDriver only supports Chrome version 81
...implies that the ChromeDriver v81 was unable to initiate/spawn a new Browsing Context i.e. Chrome Browser where is version is other then 81.0.
Your main issue is the incompatibility between the version of the binaries you are using as follows:
You mentioned about using chromedriver=80 and chrome=80 but somehow while your program execution ChromeDriver v 81.0 is used.
So, it's quite evident your have chromedriver=81.0 present within your system and is present within the system PATH variable which gets invoked while you:
driver = webdriver.Chrome()
Solution
There are two solutions:
Either you upgrade chrome to Chrome Version 81.0 level. (as per ChromeDriver v81.0 release notes)
Or you can override the default chromedriver v81.0 binary location with chromedriver v80.0 binary location as follows:
from selenium import webdriver
driver = webdriver.Chrome(executable_path=r'C:\path\to\chromedriver.exe')
driver.get('http://google.com/')

You can find a couple of relevant discussions in:
How to work with a specific version of ChromeDriver while Chrome Browser gets updated automatically through Python selenium
selenium.common.exceptions.SessionNotCreatedException: Message: session not created: This version of ChromeDriver only supports Chrome version 80
Ubuntu: selenium.common.exceptions: session not created: This version of ChromeDriver only supports Chrome version 79
First of all check latest Chrome version (This is your browser Chrome version) link
Download same version of Chrome Web Driver from this link
Do not download latest Chrome Web Driver if it does not match your Chrome Browser version.
Note: When I write this message, latest Chrome Browser version is 84 but latest Chrome Driver version is 85. I am using Chrome Driver version 84 so that Chrome Driver and Chrome Browser versions are the same.
Go to your Chrome settings -> About Chrome -> Check version
and download chromedriver from Below according to your Chrome version
https://chromedriver.chromium.org/downloads
this works for me
brew cask upgrade chromedriver
Above is deprecated on MacOs, use:
brew install chromedriver (if not already installed)
brew upgrade chromedriver
Chrome version is updating everyday so you need use exact chromedriver version according chrome version
https://chromedriver.chromium.org/downloads in this website you can download chromedrivers
The solution (at least on OSX) is:
Download the latest chromedriver file.
Unzip the downloaded file.
Search the location of the old chromedriver file on your computer and replace it with the new chromedriver file.
Right-click the chromedriver file and click open. Do not double click as Mac will not open it the proper way.
Once the file runs for the first time, you can close it and the update will have taken place.
Your Chrome Driver version needs to match your Chrome Browser version
Get you Chrome Browser version, by typing chrome://version
enter image description here
Download Chrome Driver version that matches you Chrome Browser version, form this website
https://chromedriver.chromium.org/downloads
If you are getting this error when you run stuffs on automated cluster and you are downloading the stable version of the google chrome every time then you can use the below shell script to download the compatible version of the chrome driver dynamically every time even if the stable version of the chrome gets updated.
%sh
#downloading compatible chrome driver version
#getting the current chrome browser version
**chromeVersion=$(google-chrome --product-version)**
#getting the major version value from the full version
**chromeMajorVersion=${chromeVersion%%.*}**
# setting the base url for getting the release url for the chrome driver
**baseDriverLatestReleaseURL=https://chromedriver.storage.googleapis.com/LATEST_RELEASE_**
#creating the latest release driver url based on the major version of the chrome
**latestDriverReleaseURL=$baseDriverLatestReleaseURL$chromeMajorVersion**
**echo $latestDriverReleaseURL**
#file name of the file that gets downloaded which would contain the full version of the chrome driver to download
**latestDriverVersionFileName="LATEST_RELEASE_"$chromeMajorVersion**
#downloading the file that would contain the full release version compatible with the major release of the chrome browser version
**wget $latestDriverReleaseURL**
#reading the file to get the version of the chrome driver that we should download
**latestFullDriverVersion=$(cat $latestDriverVersionFileName)**
**echo $latestFullDriverVersion**
#creating the final URL by passing the compatible version of the chrome driver that we should download
**finalURL="https://chromedriver.storage.googleapis.com/"$latestFullDriverVersion"/chromedriver_linux64.zip"**
**echo $finalURL**
**wget $finalURL**
I was able to get the compatible version of chrome browser and chrome driver using the above approach when running scheduled job on the databricks environment and it worked like a charm without any issues.
Hope it helps others in one way or other.
With Laravel (PHP) you can fix this with:
php artisan dusk:install
It will download and install the new driver.
Documentation: https://laravel.com/docs/9.x/dusk#installation
The case when your Chrome is in the middle of its update also causes this exception. In my case chromedriver was already updated, while the chrome itself was v81 instead of v83.
You can also download the correct chromedriver version from:
https://chromedriver.chromium.org/downloads
https://chromedriver.storage.googleapis.com/index.html?path=81.0.4044.138/
I too had a similar problem. And I've got a solution .. Download the matching chromedriver, and place the chromedriver under the /usr/local/bin path. It works.
The way I solved this issue was quite simple, I checked my chrome version and I had an older chromedriver in my PATH variable, so I downloaded the chromedriver version that matched my browser and replaced the old one in the PATH, so when the webdriver module looked for a chromedriver in my PATH, it would find the matching version
I had already been running a local server at the same port the session wanted to run on, and this caused the error. Shutting down that local server fixed this for me.
You need to install webdriver manager. Make sure webdriver manager it is also updated.
If you use npm:
npm install -g webdriver-manager
webdriver-manager update
If you're getting this error in Visual Studio 2019 and using Selenium.WebDriver.ChromeDriver by jsakamoto, check the version you're referencing in the packages.config file.
<package id="Selenium.WebDriver.ChromeDriver" version="89.0.4389.2300" targetFramework="net45" />
Update your NuGet package to the appropriate version and resolve the issue.
I resolved this issue by simply running Firefox (geckodriver) instead of Chrome:
rsDriver(browser = "firefox")
I got this error after a recent chrome upgrade, and also I recently updated my Mac to Big Sur. Seems cask is not part of brew command, need to use it separately.
brew install --cask chromedriver
You can handle this exception
from selenium.common.exceptions import SessionNotCreatedException
Add this function
def update_chrome():
try:
print("Updating chrome driver")
download_chrome = "wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb"
unpack_chrome = "sudo dpkg -i google-chrome-stable_current_amd64.deb"
install_chrome = "sudo apt-get -f install"
file_path = os.path.join(os.environ['HOME'], "google-chrome-stable_current_amd64.deb")
if os.path.isfile(file_path):
print("{} found\nremoving {}".format(file_path, file_path))
os.remove(file_path)
else:
print("File does not exist {}".format(file_path))
old_chrome_ver = os.popen("/usr/bin/google-chrome --version").read().strip('Google Chrome ').strip().split(".")[0]
print("Current Chrome version: {}".format(old_chrome_ver))
os.system(command=download_chrome)
sleep(2)
os.system(command=unpack_chrome)
sleep(5)
os.system(command=install_chrome)
crnt_chrome_ver = os.popen("/usr/bin/google-chrome --version").read().strip('Google Chrome ').strip().split(".")[0]
print("Current Chrome version: {}".format(crnt_chrome_ver))
if crnt_chrome_ver == old_chrome_ver:
print("Chrome version is same as before")
elif crnt_chrome_ver > old_chrome_ver:
print("Chrome version is updated from {} to {}".format(old_chrome_ver, crnt_chrome_ver))
return True
except Exception as e:
print("Error while updating chrome: {}".format(e))
return False
then call this function
try:
# Your code here
except SessionNotCreatedException as snce:
print("Session not created: {}".format(snce))
chrome_update_result = False
if recurrences == 0:
chrome_update_result = update_chrome()
if chrome_update_result:
recurrences += 1
print("Chrome updated successfully")
erisapedia_bot(state, download_dir)
return True
else:
print("Chrome update failed")
return False
What worked for me is this command:
pip install chromedriver-binary==your_chrome_version
This will uninstall the current chrome-driver that you have installed and will install a chrome-driver that matches your chrome version.
The solution is:-
Check out the chrome version of your chrome.From chrome://settings/help
Check out which version of ChromeDriver is compatible with your current
chrome version from here
download the compatible one and replace the existing ChromeDriver with
a new ChromeDriver.
Now run the code
It didn't feel like folks were answering the issue here which is: being on the latest version of beta Chrome/Chromium and not seeing the matching chromedriver version
For example, currently as of writing this, Chromium for Mac is Version 86.0.4190.0 (Developer Build) (64-bit) however the latest chromedriver versions listed are
Current stable release: ChromeDriver 83.0.4103.39
Current beta release: ChromeDriver 84.0.4147.30
If you go to https://chromedriver.chromium.org/downloads/version-selection, they provide some pointers on getting a compatible version. One of the last lines near the end mentions trying the ChromeDriver Canary build which leads to how to get it from Chromium browser snapshots.
Of course this goes without saying that using the latest experimental version is likely to have bugs
I faced this problem even after using webdriver manager. I was able to resolve the issue after specifying the exact version of chromedriver that I needed in the webddriver manager.
I was using chrome version 84 and the webdriver manager was installing the latest version of chromedriver, which was 85.0.4183.38.
I made webdriver manager to open the chromedriver version 84.0.4147.30 by writing the following command.
from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
driver = webdriver.Chrome(ChromeDriverManager(84.0.4147.30).install())
Referring to #dylanvanw answer. You might still out of luck. I found that you might have a different path that you have installed Python. In my case, I have to move Chromedriver.exe from the cache path (C:\Users\Poom.wdm\drivers\chromedriver\win32\84.0.4147.30) to C:\Python38 then it work!
Steps I took to make it work
Check your current Chrome version e.g. 81
Goto tools/nuget package manager
Select selenium chrome driver
upgrade/downgrade to the same Chrome-version you have.
Restarting the application should work.
I found a workaround to download latest version of ChromeDriver via WebDriverManager
You could try something like,
WebDriver driver = null ;
boolean oldVersion = true;
String chromeVersion = "";
try {
try{
FileReader reader = new FileReader("chromeVersion.txt") ;
BufferedReader br = new BufferedReader(reader) ;
String line;
while ((line = br.readLine()) != null){
chromeVersion = line.trim();
}
reader.close();
} catch (IOException e ) {}
WebDriverManager.chromedriver().version(chromeVersion).setup();
driver = new ChromeDriver() ;
} catch (Exception e) {
oldVersion = false;
String err = e.getMessage() ;
chromeVersion = err.split("version is")[1].split("with binary path")[0].trim();
try{
FileWriter writer = new FileWriter("chromeVersion.txt", true) ;
writer.write(chromeVersion) ;
writer.close();
} catch (IOException er ) {}
}
if (!oldVersion){
WebDriverManager.chromedriver().version(chromeVersion).setup();
driver = new ChromeDriver() ;
}
driver.get("https://www.google.com") ;
I got this error when the chrome driver was not closed properly. Eg, if I try to find something and click it and it doesn't exist, the driver throws an exception and the thread ended there ( I did not close the driver ).
So, when I ran the same method again later where I had to reinitialize the driver, the driver didn't initialize and it threw the exception.
My solve was simply to wrap the selenium tasks in a try catch and close the driver properly
I am trying to launch chrome with an URL, the browser launches and it does nothing after that.
I am seeing the below error after 1 minute:
Unable to open browser with url: 'https://www.google.com' (Root cause: org.openqa.selenium.WebDriverException: unknown error: DevToolsActivePort file doesn't exist
(Driver info: chromedriver=2.39.562718 (9a2698cba08cf5a471a29d30c8b3e12becabb0e9),platform=Windows NT 10.0.15063 x86_64) (WARNING: The server did not provide any stacktrace information)
My configuration:
Chrome : 66
ChromeBrowser : 2.39.56
P.S everything works fine in Firefox
Thumb rule
A common cause for Chrome to crash during startup is running Chrome as root user (administrator) on Linux. While it is possible to work around this issue by passing --no-sandbox flag when creating your WebDriver session, such a configuration is unsupported and highly discouraged. You need to configure your environment to run Chrome as a regular user instead.
This error message...
org.openqa.selenium.WebDriverException: unknown error: DevToolsActivePort file doesn't exist
...implies that the ChromeDriver was unable to initiate/spawn a new WebBrowser i.e. Chrome Browser session.
Your code trials and the versioning information of all the binaries would have given us some hint about what's going wrong.
However as per Add --disable-dev-shm-usage to default launch flags seems adding the argument --disable-dev-shm-usage will temporary solve the issue.
If you desire to initiate/span a new Chrome Browser session you can use the following solution:
System.setProperty("webdriver.chrome.driver", "C:\\path\\to\\chromedriver.exe");
ChromeOptions options = new ChromeOptions();
options.addArguments("start-maximized"); // open Browser in maximized mode
options.addArguments("disable-infobars"); // disabling infobars
options.addArguments("--disable-extensions"); // disabling extensions
options.addArguments("--disable-gpu"); // applicable to windows os only
options.addArguments("--disable-dev-shm-usage"); // overcome limited resource problems
options.addArguments("--no-sandbox"); // Bypass OS security model
WebDriver driver = new ChromeDriver(options);
driver.get("https://google.com");
disable-dev-shm-usage
As per base_switches.cc disable-dev-shm-usage seems to be valid only on Linux OS:
#if defined(OS_LINUX) && !defined(OS_CHROMEOS)
// The /dev/shm partition is too small in certain VM environments, causing
// Chrome to fail or crash (see http://crbug.com/715363). Use this flag to
// work-around this issue (a temporary directory will always be used to create
// anonymous shared memory files).
const char kDisableDevShmUsage[] = "disable-dev-shm-usage";
#endif
In the discussion Add an option to use /tmp instead of /dev/shm David mentions:
I think it would depend on how are /dev/shm and /tmp mounted.
If they are both mounted as tmpfs I'm assuming there won't be any difference.
if for some reason /tmp is not mapped as tmpfs (and I think is mapped as tmpfs by default by systemd), chrome shared memory management always maps files into memory when creating an anonymous shared files, so even in that case shouldn't be much difference. I guess you could force telemetry tests with the flag enabled and see how it goes.
As for why not use by default, it was a pushed back by the shared memory team, I guess it makes sense it should be useing /dev/shm for shared memory by default.
Ultimately all this should be moving to use memfd_create, but I don't think that's going to happen any time soon, since it will require refactoring Chrome memory management significantly.

Outro
Here is the link to the Sandbox story.
I started seeing this problem on Monday 2018-06-04. Our tests run each weekday. It appears that the only thing that changed was the google-chrome version (which had been updated to current) JVM and Selenium were recent versions on Linux box ( Java 1.8.0_151, selenium 3.12.0, google-chrome 67.0.3396.62, and xvfb-run).
Specifically adding the arguments "--no-sandbox" and "--disable-dev-shm-usage" stopped the error.
I'll look into these issues to find more info about the effect, and other questions as in what triggered google-chrome to update.
ChromeOptions options = new ChromeOptions();
...
options.addArguments("--no-sandbox");
options.addArguments("--disable-dev-shm-usage");
We were having the same issues on our jenkins slaves (linux machine) and tried all the options above.
The only thing helped is setting the argument
chrome_options.add_argument('--headless')
But when we investigated further, noticed that XVFB screen doesn't started property and thats causing this error. After we fix XVFB screen, it resolved the issue.
I had the same problem in python. The above helped. Here is what I used in python -
chrome_options = Options()
chrome_options.add_argument('--headless')
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--disable-dev-shm-usage')
driver = webdriver.Chrome('/path/to/your_chrome_driver_dir/chromedriver',chrome_options=chrome_options)
I was facing the same issue recently and after some trial and error it worked for me as well.

In my case in the following environment:
Windows 10
Python 3.7.5
Google Chrome version 80 and corresponding ChromeDriver in the path C:\Windows
selenium 3.141.0
I needed to add the arguments --no-sandbox and --remote-debugging-port=9222 to the ChromeOptions object and run the code as administrator user by lunching the Powershell/cmd as administrator.
Here is the related piece of code:
options = webdriver.ChromeOptions()
options.add_argument('headless')
options.add_argument('--disable-infobars')
options.add_argument('--disable-dev-shm-usage')
options.add_argument('--no-sandbox')
options.add_argument('--remote-debugging-port=9222')
driver = webdriver.Chrome(options=options)
I ran into this problem on Ubuntu 20 with Python Selenium after first downloading the chromedriver separately and then using sudo apt install chromium-browser Even though they were the same version this kept happening.
My fix was to use the provided chrome driver that came with the repo package located at
/snap/bin/chromium.chromedriver
driver = webdriver.Chrome(chrome_options=options, executable_path='/snap/bin/chromium.chromedriver')
Update:
I am able to get through the issue and now I am able to access the chrome with desired url.
Results of trying the provided solutions:
I tried all the settings as provided above but I was unable to resolve the issue
Explanation regarding the issue:
As per my observation DevToolsActivePort file doesn't exist is caused when chrome is unable to find its reference in scoped_dirXXXXX folder.
Steps taken to solve the issue
I have killed all the chrome processes and chrome driver processes.
Added the below code to invoke the chrome
System.setProperty("webdriver.chrome.driver","pathto\\chromedriver.exe");
ChromeOptions options = new ChromeOptions();
options.setExperimentalOption("useAutomationExtension", false);
WebDriver driver = new ChromeDriver(options);
driver.get(url);
Using the above steps I was able to resolve the issue.
Thanks for your answers.
In my case it was problem with CI Agent account on ubuntu server, I solved this using custom --user-data-dir
chrome_options.add_argument('--user-data-dir=~/.config/google-chrome')
My account used by CI Agent didn't have necessary permissions, what was interesting everything was working on root account
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
chrome_options = Options()
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--headless')
chrome_options.add_argument('--disable-gpu')
chrome_options.add_argument('--disable-dev-shm-usage')
chrome_options.add_argument('--profile-directory=Default')
chrome_options.add_argument('--user-data-dir=~/.config/google-chrome')
driver = webdriver.Chrome(options=chrome_options)
url = 'https://www.google.com'
driver.get(url)
get_url = driver.current_url
print(get_url)
There is lot of possible reasons for the RESPONSE InitSession ERROR unknown error: DevToolsActivePort file doesn't exist error message (as we can see from the number of answers for this question). So let's dive deeper to explain what exactly this error message means.
According to chromedriver source code the message is created in ParseDevToolsActivePortFile method. This method is called from the loop after launching chrome process.
In the loop the driver check if the chrome process is still running and if the ParseDevToolsActivePortFile file was already created by chrome. There is a hardcoded 60s timeout for this loop.
I see two possible reasons for this message:
Chrome is really slow during startup - for example due to lack of system resources - mainly CPU or memory. In this case it can happen that sometimes chrome manage to start in time limit and sometimes not.
There is another issue which prevents chrome to start - missing or broken dependency, wrong configuration etc. In such case this error message is not really helpful and you should find another log message which explain the true reason of the failure.
It happens when chromedriver fails to figure out what debugging port chrome is using.
One possible cause is an open defect with HKEY_CURRENT_USER\Software\Policies\Google\Chrome\UserDataDir
But in my last case, it was some other unidentified cause.
Fortunately setting port number manually worked:
final String[] args = { "--remote-debugging-port=9222" };
options.addArguments(args);
WebDriver driver = new ChromeDriver(options);
As stated in this other answer:
This error message... implies that the ChromeDriver was unable to initiate/spawn a new WebBrowser i.e. Chrome Browser session.
Among the possible causes, I would like to mention the fact that, in case you are running an headless Chromium via Xvfb, you might need to export the DISPLAY variable: in my case, I had in place (as recommended) the --disable-dev-shm-usage and --no-sandbox options, everything was running fine, but in a new installation running the latest (at the time of writing) Ubuntu 18.04 this error started to occurr, and the only possible fix was to execute an export DISPLAY=":20" (having previously started Xvfb with Xvfb :20&).
You can get this error simply for passing bad arguments to Chrome. For example, if I pass "headless" as an arg to the C# ChromeDriver, it fires up great. If I make a mistake and use the wrong syntax, "--headless", I get the DevToolsActivePort file doesn't exist error.
I was stuck on this for a very long time and finally fixed it by adding this an additional option:
options.addArguments("--crash-dumps-dir=/tmp")
I know it's an old question and it already has a lot of answers. However, I ran into this issue, bumped into this thread and none of the proposed solutions helped. After spending a few days(!) on it I finally found a solution:
My problem was that I was using the selenium/standalone-chrome image on a MacBook with M1 chip. After switching to seleniarm/standalone-chromium everything finally started to work.
I had the same issue, but in my case chrome previously was installed in user temp folder, after that was reinstalled to Program files. So any of solution provided here was not help me. But if provide path to chrome.exe all works:
chromeOptions.setBinary("C:\\Program Files (x86)\\Google\\Chrome\\Application\\chrome.exe");
I hope this helps someone =)
In my case it happened when I've tried to use my default user profile:
...
options.addArguments("user-data-dir=D:\\MyHomeDirectory\\Google\\Chrome\\User Data");
...
This triggered chrome to reuse processes already running in background, in such a way, that process started by chromedriver.exe was simply ended.
Resolution: kill all chrome.exe processes running in background.
update capabilities in conf.js as
exports.config = {
seleniumAddress: 'http://localhost:4444/wd/hub',
specs: ['todo-spec.js'],
capabilities: {
browserName: 'chrome',
chromeOptions: {
args: ['--disable-gpu', '--no-sandbox', '--disable-extensions', '--disable-dev-shm-usage']
}
},
};
Old question but a similar issue nearly drove me to insanity so sharing my solution. None of the other suggestions fixed my issue.
When I updated my Docker image Chrome installation from an old version to Chrome 86, I got this error. My setup was not identical but we were instantiating Chrome through a selenium webdriver.
The solution was to pass the options as goog:chromeOptions hash instead of chromeOptions hash. I truly don't know if this was a Selenium, Chrome, Chromedriver, or some other update, but maybe some poor soul will find solace in this answer in the future.
For Ubuntu 20 it did help me to use my systems chromium driver instead of the downloaded one:
# chromium which
/snap/bin/chromium
driver = webdriver.Chrome('/snap/bin/chromium.chromedriver',
options=chrome_options)
And for the downloaded webdriver looks like it needs the remote debug port --remote-debugging-port=9222 to be set, as in one of the answers (by Soheil Pourbafrani):
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument("--remote-debugging-port=9222")
driver = webdriver.Chrome('<path_to>/chromedriver', options=chrome_options)
Date 9/16/2021
Everything works fine running chrome with selenium locally with python inside the docker hosted ubuntu container. When attempting to run from Jenkins the error above is returned WebDriverException: unknown error: DevToolsActivePort
Environment:
-Ubuntu21.04 inside a docker container with RDP access.
-chromedriver for chrome version: 93
Solution:
Inside the python file that starts the browser I had to set the DISPLAY environment variable using the following lines:
import os
os.environ['DISPLAY'] = ':10.0'
#DISPLAY_VAR = os.environ.get('DISPLAY')
#print("DISPLAY_VAR:", DISPLAY_VAR)
In my case, I was trying to create a runnable jar on Windows OS with chrome browser and want to run the same on headless mode in unix box with CentOs on it. And I was pointing my binary to a driver that I have downloaded and packaged with my suite. For me, this issue continue to occur irrespective of adding the below:
ChromeOptions options = new ChromeOptions();
options.addArguments("--headless");
options.addArguments("--no-sandbox");
System.setProperty("webdriver.chrome.args", "--disable-logging");
System.setProperty("webdriver.chrome.silentOutput", "true");
options.setBinary("/pointing/downloaded/driver/path/in/automationsuite");
options.addArguments("--disable-dev-shm-usage"); // overcome limited resource problems

Solution that I've tried and worked for me is, download the chrome and its tools on the host VM/Unix box, install and point the binary to this in the automation suite and bingo! It works :)
Download command:
wget https://dl.google.com/linux/direct/google-chrome-stable_current_x86_64.rpm
Install command:
sudo yum install -y ./google-chrome-stable_current_*.rpm
Update suite with below binary path of google-chrome:
options.setBinary("/opt/google/chrome/google-chrome");
And.. it works!
I also faced this issue while integrating with jenkins server, I was used the root user for jenkin job, the issue was fixed when I changed the user to other user. I am not sure why this error occurs for the root user.
Google Chrome Version 71.0
ChromeDriver Version 2.45
CentOS7 Version 1.153
I run selenium tests with Jenkins running on an Ubuntu 18 LTS linux. I had this error until I added the argument 'headless' like this (and some other arguments):
ChromeOptions options = new ChromeOptions();
options.addArguments("headless"); // headless -> no browser window. needed for jenkins
options.addArguments("disable-infobars"); // disabling infobars
options.addArguments("--disable-extensions"); // disabling extensions
options.addArguments("--disable-dev-shm-usage"); // overcome limited resource problems
options.addArguments("--no-sandbox"); // Bypass OS security model
ChromeDriver driver = new ChromeDriver(options);
driver.get("www.google.com");
Had the same issue. I am running the selenium script on Google cloud VM.
options.addArguments("--headless");
The above line resolved my issue. I removed the other optional arguments. I think the rest lines of code mentioned in other answers did not have any effect on resolving the issue on the cloud VM.
in my case, when i changed the google-chrome and chromedriver version, the error was fixed :)
#google-chrome version
[root#localhost ~]# /usr/bin/google-chrome --version
Google Chrome 83.0.4103.106
#chromedriver version
[root#localhost ~]# /usr/local/bin/chromedriver -v
ChromeDriver 83.0.4103.14 (be04594a2b8411758b860104bc0a1033417178be-refs/branch-heads/4103#{#119})
ps: selenium verison was 3.9.1
No solution worked for my. But here is a workaround:
maxcounter=5
for counter in range(maxcounter):
try:
driver = webdriver.Chrome(chrome_options=options,
service_log_path=logfile,
service_args=["--verbose", "--log-path=%s" % logfile])
break
except WebDriverException as e:
print("RETRYING INITIALIZATION OF WEBDRIVER! Error: %s" % str(e))
time.sleep(10)
if counter==maxcounter-1:
raise WebDriverException("Maximum number of selenium-firefox-webdriver-retries exceeded.")
It seems there are many possible causes for this error. In our case, the error happened because we had the following two lines in code:
System.setProperty("webdriver.chrome.driver", chromeDriverPath);
chromeOptions.setBinary(chromeDriverPath);
It's solved by removing the second line.
I ran into same issue, i am using UBUNTU, PYTHON and OPERA browser. in my case the problem was originated because i had an outdated version of operadriver.
Solution:
1. Make sure you install latest opera browser version ( do not use opera beta or opera developer), for that go to the official opera site and download from there the latest opera_stable version.
Install latest opera driver (if you already have an opera driver install, you have to remove it first use sudo rm ...)
wget https://github.com/operasoftware/operachromiumdriver/releases/download/v.80.0.3987.100/operadriver_linux64.zip
unzip operadriver_linux64.zip
sudo mv operadriver /usr/bin/operadriver
sudo chown root:root /usr/bin/operadriver
sudo chmod +x /usr/bin/operadriver
in my case latest was 80.0.3987 as you can see
Additionally i also installed chromedriver (but since i did it before testing, i do not know of this is needed) in order to install chromedriver, follow the steps on previous step :v
Enjoy and thank me!
Sample selenium code
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
driver = webdriver.Opera()
driver.get("http://www.python.org")
assert "Python" in driver.title
elem = driver.find_element_by_name("q")
elem.clear()
elem.send_keys("pycon")
elem.send_keys(Keys.RETURN)
assert "No results found." not in driver.page_source
driver.quit()
I came across the same problem, in my case there are two different common user userA and userB in Linux system.
userA first run the selinium programe which start chrome browswer with ChromeDriver successfully, when it came to userB, the DevToolsActivePort file doesn't exist error occur.
I tried the --remote-debugging-port=9222 option, but it lead to a new exception:
selenium.common.exceptions.WebDriverException: Message: chrome not reachable
The I ran google-chome directory and see the following error:
mkdir /tmp/Crashpad/new: Permission denied (13)
The I search the problem and got this:
https://johncylee.github.io/2022/05/14/chrome-headless-%E6%A8%A1%E5%BC%8F%E4%B8%8B-devtoolsactiveport-file-doesn-t-exist-%E5%95%8F%E9%A1%8C/
chrome_options.add_argument(f"--crash-dumps-dir={os.path.expanduser('~/tmp/Crashpad')}")
