我试图用一个URL启动chrome浏览器,浏览器启动后,它什么也不做。

1分钟后我看到如下错误:

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)

我的配置:

Chrome浏览器:66 ChromeBrowser: 2.39.56

又及,在Firefox中一切都很好


当前回答

我也经历过这个问题,提出的解决方案似乎都不起作用。然后我发现问题是我在WSL版本1上运行,似乎chromedriver与windows浏览器一起工作,而不是与aptitude安装的浏览器。

为了使它与WSL版本1和版本2兼容,我发现(并在debian WSLv2和ubuntu WSLv1中进行了测试,它可以工作),该平台的版本显示的单词Microsoft的第一个大写字母。

所以解决方案是这样的:

    import platform
    from selenium.webdriver.chrome.service import Service as ChromeService
    from seleniumwire import webdriver

    chromedriver = 'chromedriver.exe'
    
    # According to:
    # https://stackoverflow.com/a/71879688/7019069
    # When using WSL v1 the chromedriver.exe of local chrome of windows is used
    # In WSL v2 (updated version) it does work using the installation shown in the README.md)
    # And according to
    # https://github.com/microsoft/WSL/issues/4555
    # It is possible to differentiate the version of WSL by the first uppercase of the platform 
    # version of Microsoft. Therefore only the linux chromedriver is used if that word is matched 
    # in the platform of the driver. 
    if platform.system() == 'Linux' and not re.search(re.escape('Microsoft'), platform.platform()):
        chromedriver = 'chromedriver'

    driver_path = os.path.join(drivers_path, chromedriver)
  service = ChromeService(driver_path)

    driver = webdriver.Chrome(
        service=service,
        options=__get_chrome_options(headless)
    )

其他回答

我们在jenkins slave (linux机器)上也遇到了同样的问题,并尝试了上述所有选项。

唯一有帮助的就是设定论点

chrome_options.add_argument('--headless')

但是当我们进一步调查时,注意到XVFB屏幕没有启动属性,这导致了这个错误。在我们修复XVFB屏幕后,它解决了这个问题。

没有解决方法对我有效。但这里有一个变通办法:

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.")

更新:

我能够通过这个问题,现在我能够访问chrome所需的url。

对所提供解决方案的尝试结果:

我尝试了上面提供的所有设置,但我无法解决这个问题

关于问题的解释:

根据我的观察,DevToolsActivePort文件不存在的原因是chrome无法在scoped_dirXXXXX文件夹中找到它的引用。

为解决该问题所采取的步骤

我已经杀死了所有的chrome进程和chrome驱动程序进程。 添加下面的代码来调用chrome System.setProperty(“webdriver.chrome.driver”、“pathto \ \ chromedriver.exe”); ChromeOptions选项=新的ChromeOptions(); 选项。setExperimentalOption(“useAutomationExtension”,假); WebDriver驱动=新的ChromeDriver(选项); driver.get (url);

使用上述步骤,我能够解决这个问题。

谢谢你的回答。

我在python中遇到了同样的问题。以上这些都有帮助。这是我在python中使用的

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)

正如在另一个答案中所述:

此错误消息…这意味着ChromeDriver无法启动/生成一个新的WebBrowser,即Chrome浏览器会话。

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&).
