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)
)

当chromedriver无法找出chrome正在使用的调试端口时，就会发生这种情况。
一个可能的原因是HKEY_CURRENT_USER\Software\Policies\谷歌\Chrome\UserDataDir的开放缺陷
但在我的最后一个病例中，是其他一些不明原因。
幸运的是，手动设置端口号:
final String[] args = { "--remote-debugging-port=9222" };
options.addArguments(args);
WebDriver driver = new ChromeDriver(options);
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)
在我的例子中，我在Kubernetes环境中不能使用默认的TMPDIR，因为它会用垃圾填满临时目录。
所以我用这个来使用不同的tmpdir:
driver = new ChromeDriver(new ChromeDriverService.Builder()
.withEnvironment(ImmutableMap.of("TMPDIR", customTmpPath))
.build(), options);
但现在我把所有东西都升级到最新版本，这似乎不再管用了。我需要找到一种新的方法来做这件事。
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&).
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。
