[python] Selenium: WebDriverException:Chrome failed to start: crashed as google-chrome is no longer running so ChromeDriver is assuming that Chrome has crashed

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:

Chrome_binary_expected_location

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:

  • Python Solution:

    from selenium import webdriver
    from selenium.webdriver.chrome.options import Options
    
    options = Options()
    options.binary_location = "C:\\path\\to\\chrome.exe"    #chrome binary location specified here
    options.add_argument("--start-maximized") #open Browser in maximized mode
    options.add_argument("--no-sandbox") #bypass OS security model
    options.add_argument("--disable-dev-shm-usage") #overcome limited resource problems
    options.add_experimental_option("excludeSwitches", ["enable-automation"])
    options.add_experimental_option('useAutomationExtension', False)
    driver = webdriver.Chrome(options=options, executable_path=r'C:\path\to\chromedriver.exe')
    driver.get('http://google.com/')
    
  • Java Solution:

    System.setProperty("webdriver.chrome.driver", "C:\\Utility\\BrowserDrivers\\chromedriver.exe");
    ChromeOptions opt = new ChromeOptions();
    opt.setBinary("C:\\Program Files (x86)\\Google\\Chrome\\Application\\chrome.exe");  //chrome binary location specified here
    options.addArguments("start-maximized");
    options.setExperimentalOption("excludeSwitches", Collections.singletonList("enable-automation"));
    options.setExperimentalOption("useAutomationExtension", false);
    WebDriver driver = new ChromeDriver(opt);
    driver.get("https://www.google.com/");
