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

你可以得到这个错误简单地传递坏的参数Chrome。例如,如果我将“headless”作为参数传递给c# ChromeDriver,它会很好地启动。如果我犯了一个错误,使用了错误的语法,“——headless”,我得到DevToolsActivePort文件不存在错误。

其他回答

我有同样的问题,但在我的情况下,chrome之前安装在用户临时文件夹,之后被重新安装到程序文件。所以这里提供的任何解决方案都帮不了我。但是如果提供了chrome.exe的路径就可以了:

chromeOptions.setBinary("C:\\Program Files (x86)\\Google\\Chrome\\Application\\chrome.exe");

我希望这能帮助到一些人=)

更新conf.js中的功能

exports.config = {
  seleniumAddress: 'http://localhost:4444/wd/hub',
  specs: ['todo-spec.js'],
  capabilities: {
    browserName: 'chrome',
    chromeOptions: {
      args: ['--disable-gpu', '--no-sandbox', '--disable-extensions', '--disable-dev-shm-usage']
    }
  },

};

我被这个问题困扰了很长一段时间,最后通过添加一个额外的选项来解决它:

options.addArguments(”——crash-dumps-dir = / tmp”)

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.")

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)
    )
