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

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

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)
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&).
我在Docker容器中通过Behat/Mink和Selenium运行Chrome时也遇到了同样的问题。经过一番折腾，我得出了如下结论。Yml提供上面提到的开关。请注意，要使它成功运行，所有这些都是必需的。
default:
extensions:
Behat\MinkExtension:
base_url: https://my.app/
default_session: selenium2
selenium2:

args:

- "no-sandbox"
- "disable-dev-shm-usage"
在我的情况下，我试图用chrome浏览器在Windows操作系统上创建一个可运行的jar，并希望在unix盒子上运行CentOs的无头模式。我把二进制文件指向一个我已经下载并打包在我的套件中的驱动程序。对我来说，这个问题继续发生，不管添加以下内容:
ChromeOptions options = new ChromeOptions();
options.addArguments("--headless");
options.addArguments("--no-sandbox");
System.setProperty("webdriver.chrome.args", "--disable-logging");
System.setProperty("webdriver.chrome.silentOutput", "true");
options.setBinary("/pointing/downloaded/driver/path/in/automationsuite");
options.addArguments("--disable-dev-shm-usage"); // overcome limited resource problems
options.addArguments("disable-infobars"); // disabling infobars
options.addArguments("--disable-extensions"); // disabling extensions
options.addArguments("--disable-gpu"); // applicable to windows os only
options.addArguments("--disable-dev-shm-usage"); // overcome limited resource problems
options.addArguments("window-size=1024,768"); // Bypass OS security model
options.addArguments("--log-level=3"); // set log level
options.addArguments("--silent");//
options.setCapability("chrome.verbose", false); //disable logging
driver = new ChromeDriver(options);
我尝试过并为我工作的解决方案是，在主机VM/Unix盒子上下载chrome及其工具，在自动化套件中安装并指向此二进制文件，然后就完成了!它是有效的:)
下载命令:
wget https://dl.google.com/linux/direct/google-chrome-stable_current_x86_64.rpm
安装命令:
sudo yum install -y ./google-chrome-stable_current_*.rpm
更新套件包含以下google-chrome二进制路径:
options.setBinary("/opt/google/chrome/google-chrome");
和. .它的工作原理!
