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

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)
    )

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");

在尝试在Linux服务器上运行selenium时遇到了同样的问题,尝试降级你的chrome版本,它对我有用吗

从这里选择版本

http://170.210.201.179/linux/chrome/deb/pool/main/g/google-chrome-stable/

也有同样的问题。我正在谷歌云虚拟机上运行selenium脚本。

options.addArguments("--headless");

上面这句话解决了我的问题。我删除了其他可选参数。我认为其他答案中提到的其余代码行对解决云VM上的问题没有任何影响。

对于Ubuntu 20,它确实帮助我使用我的系统铬驱动程序,而不是下载的那个:

# chromium which
/snap/bin/chromium

driver = webdriver.Chrome('/snap/bin/chromium.chromedriver',
                          options=chrome_options)

对于下载的web驱动程序来说,它看起来需要远程调试端口——remote-debugging-port=9222来设置,就像其中一个答案(由Soheil Pourbafrani):

chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument("--remote-debugging-port=9222")
driver = webdriver.Chrome('<path_to>/chromedriver', options=chrome_options)

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。
