I'm aware there are several answers concerning this question but nothing has worked for me so far so therefor i'm posting a new question.

Recently i switched computers and since then I can't launch chrome with selenium. i've also tried firefox but the browser just doesn't lanch.

from selenium import webdriver



d = webdriver.Chrome('/home/PycharmProjects/chromedriver')



d.get('https://www.google.nl/')

i get the following error:

selenium.common.exceptions.WebDriverException: Message: unknown error: Chrome failed to start: crashed

  (unknown error: DevToolsActivePort file doesn't exist)

  (The process started from chrome location /opt/google/chrome/google-chrome is no longer running, so ChromeDriver is assuming that Chrome has crashed.)

  (Driver info: chromedriver=2.43.600233, platform=Linux 4.15.0-38-generic x86_64)

i have the latest chrome version and chromedriver installed

EDIT:
After trying @b0sss solution i am getting the following error.

selenium.common.exceptions.WebDriverException: Message: unknown error: Chrome failed to start: crashed

  (chrome not reachable)

  (The process started from chrome location /opt/google/chrome/google-chrome is no longer running, so chromedriver is assuming that Chrome has crashed.)

  (Driver info: chromedriver=2.43.600233 (523efee95e3d68b8719b3a1c83051aa63aa6b10d),platform=Linux 4.15.0-38-generic x86_64)

This error message...

selenium.common.exceptions.WebDriverException: Message: unknown error: Chrome failed to start: crashed

  (unknown error: DevToolsActivePort file doesn't exist)

  (The process started from chrome location /opt/google/chrome/google-chrome is no longer running, so ChromeDriver is assuming that Chrome has crashed.)

...implies that the ChromeDriver was unable to initiate/spawn a new WebBrowser i.e. Chrome Browser session.

Your main issue is the Chrome browser is not installed at the default location within your system.

The server i.e. ChromeDriver expects you to have Chrome installed in the default location for each system as per the image below:

¹For Linux systems, the ChromeDriver expects /usr/bin/google-chrome to be a symlink to the actual Chrome binary.

Solution

In case you are using a Chrome executable in a non-standard location you have to override the Chrome binary location. as follows:

Try to download HERE and use this latest chrome driver version.

https://sites.google.com/a/chromium.org/chromedriver/downloads

EDIT:

Try this:

chrome_options = Options()

chrome_options.add_argument('--headless')

chrome_options.add_argument('--no-sandbox')

chrome_options.add_argument('--disable-dev-shm-usage')

d = webdriver.Chrome('/home/PycharmProjects/chromedriver',chrome_options=chrome_options)

d.get('https://www.google.nl/')

I encountered the exact problem running on docker container (in build environment). After ssh into the container, I tried running the test manually and still encountered

(unknown error: DevToolsActivePort file doesn't exist)

     (The process started from chrome location /usr/bin/google-chrome-stable is 

      no longer running, so ChromeDriver is assuming that Chrome has crashed.)

When I tried running chrome locally /usr/bin/google-chrome-stable, error message

Running as root without --no-sandbox is not supported

I checked my ChromeOptions and it was missing --no-sandbox, which is why it couldn't spawn chrome.

capabilities = Selenium::WebDriver::Remote::Capabilities.chrome(

  chromeOptions: { args: %w(headless --no-sandbox disable-gpu window-size=1920,1080) }

)

Assuming that you already downloaded chromeDriver, this error is also occurs when already multiple chrome tabs are open.

If you close all tabs and run again, the error should clear up.
