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

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&).

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:
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");

在docker托管的ubuntu容器中使用python在本地运行chrome和selenium，一切都很好。当试图运行从Jenkins上面的错误返回WebDriverException:未知错误:DevToolsActivePort
环境:
-Ubuntu21.04在docker容器内，支持RDP访问。
chrome版本:93
解决方案: 在启动浏览器的python文件中，我必须使用以下行设置DISPLAY环境变量:
import os
os.environ['DISPLAY'] = ':10.0'
#DISPLAY_VAR = os.environ.get('DISPLAY')
#print("DISPLAY_VAR:", DISPLAY_VAR)
我在与jenkins服务器集成时也遇到了这个问题，我使用了jenkin工作的根用户，当我将用户更改为其他用户时，这个问题得到了解决。我不确定为什么根用户会出现这个错误。
谷歌Chrome浏览器版本71.0 ChromeDriver版本2.45 CentOS7版本1.153
我使用铬，但我已经创建了一个shell脚本称为铬，只是为了便于我从dmenu打开浏览器。
#!/bin/bash
/usr/bin/chromium
Chrome驱动程序在PATH中寻找Chrome并执行。结果我得到了同样的错误。
org.openqa.selenium.WebDriverException: unknown error: Chrome failed to start: exited normally.
(unknown error: DevToolsActivePort file doesn't exist)
(The process started from chrome location /home/s1n7ax/.local/share/s1n7ax/bin/chrome is no longer running, so ChromeDriver is assuming that Chrome has crashed.)

我只是删除了shell脚本，并添加了一个到chromium的软链接。现在一切正常。
