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

由于这是针对这类错误的最活跃的消息，所以我想提一下我的解决方案(在花了几个小时来修复这个问题之后)。
On Ubuntu 18.04, using Chrome 70 and Chromedriver 2.44, and Python3 I kept getting the same DevToolsActivePort error, even when I disabled all options listed above. The chromedriver log file as well as ps showed that the chromedriver I set in chrome_options.binary_location was running, but it always gave DevToolsActivePort error. When I removed chrome_options.binary_location='....' and add it to webdriver creation, I get it working fine. webdriver.Chrome('/path to ... /chromedriver',chrome_options=chrome_options)
感谢大家的意见，让我理解并解决了这个问题。

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)
)
我通过安装yum -y install gtk3-devel gtk3-dev -docs”来解决这个问题，它可以正常工作
我的工作环境是:
Selenium Version 3.12.0
ChromeDriver Version v2.40
Chrome 68 level
之前:
后:
这个错误似乎有很多可能的原因。在我们的例子中，错误发生是因为我们有以下两行代码:
System.setProperty("webdriver.chrome.driver", chromeDriverPath);
chromeOptions.setBinary(chromeDriverPath);
它通过去掉第二行来解决。
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);
我用Jenkins在Ubuntu 18 LTS linux上运行selenium测试。我有这个错误，直到我像这样添加了参数'headless'(以及其他一些参数):
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");
