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

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");

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”)
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:
在我的例子中，当我试图使用我的默认用户配置文件时，它发生了:
...
options.addArguments("user-data-dir=D:\\MyHomeDirectory\\Google\\Chrome\\User Data");
...
这触发chrome重用已经在后台运行的进程，以这种方式，由chromedriver.exe启动的进程简单地结束。
解决方法:关闭所有在后台运行的chrome.exe进程。
核心的答案 正确的解决方案:不使用root用户运行Chrome二进制 更多细节请参考另一个帖子的回答:未知错误:DevToolsActivePort文件不存在
