WebDriverException: unknown error: DevToolsActivePort file doesn't exist while trying to initiate Chrome Browser

Question

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         


        

Answer 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.")

Answer 2

I use chromium but I have created a shell script called chrome just to be easy for me to open the browser from dmenu.

#!/bin/bash

/usr/bin/chromium

Chrome driver looking for chrome in PATH and executes that. In result I got the same error.

org.openqa.selenium.WebDriverException: unknown error: Chrome failed to start: exited normally.
  (unknown error: DevToolsActivePort file doesn't exist)
  (The process started from chrome location /home/s1n7ax/.local/share/s1n7ax/bin/chrome is no longer running, so ChromeDriver is assuming that Chrome has crashed.)
Build info: version: '3.141.59', revision: 'e82be7d358', time: '2018-11-14T08:17:03'
System info: host: 's1n7ax', ip: '127.0.1.16', os.name: 'Linux', os.arch: 'amd64', os.version: '5.4.70-1-lts', java.version: '11.0.8'
Driver info: driver.version: ChromeDriver
remote stacktrace: #0 0x56030c96dd99 <unknown>

I just removed the shell script and added a soft link to chromium. Everything working now.

Answer 3

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)

Answer 4

I was facing the same issue recently and after some trial and error it worked for me as well.

MUST BE ON TOP:

options.addArguments("--no-sandbox"); //has to be the very first option

BaseSeleniumTests.java

public abstract class BaseSeleniumTests {

    private static final String CHROMEDRIVER_EXE = "chromedriver.exe";
    private static final String IEDRIVER_EXE = "IEDriverServer.exe";
    private static final String FFDRIVER_EXE = "geckodriver.exe";
    protected WebDriver driver;

    @Before
    public void setUp() {
        loadChromeDriver();
    }

    @After
    public void tearDown() {
        if (driver != null) {
            driver.close();
            driver.quit();
        }
    }

    private void loadChromeDriver() {
        ClassLoader classLoader = getClass().getClassLoader();
        String filePath = classLoader.getResource(CHROMEDRIVER_EXE).getFile();
        DesiredCapabilities capabilities = DesiredCapabilities.chrome();
        ChromeDriverService service = new ChromeDriverService.Builder()
                .usingDriverExecutable(new File(filePath))
                .build();
        ChromeOptions options = new ChromeOptions();
        options.addArguments("--no-sandbox"); // Bypass OS security model, MUST BE THE VERY FIRST OPTION
        options.addArguments("--headless");
        options.setExperimentalOption("useAutomationExtension", false);
        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.merge(capabilities);
        this.driver = new ChromeDriver(service, options);
    }

}

GoogleSearchPageTraditionalSeleniumTests.java

@RunWith(SpringRunner.class)
@SpringBootTest
public class GoogleSearchPageTraditionalSeleniumTests extends BaseSeleniumTests {

    @Test
    public void getSearchPage() {
        this.driver.get("https://www.google.com");
        WebElement element = this.driver.findElement(By.name("q"));
        assertNotNull(element);
    }

Answer 5

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.

Answer 6

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");
