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
当前回答
我在Ubuntu 20和Python Selenium上遇到了这个问题，我首先单独下载了chromedriver，然后使用sudo apt install chromium-browser，尽管它们是同一个版本，但这种情况一直发生。
我的修复是使用提供的chrome驱动程序，附带的回购包位于
/snap/bin/chromium.chromedriver
driver = webdriver.Chrome(chrome_options=options, executable_path='/snap/bin/chromium.chromedriver')
其他回答
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)
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.)

Driver info: driver.version: ChromeDriver

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。
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。
在我的情况下，这是ubuntu服务器上的CI代理帐户的问题，我用自定义——user-data-dir解决了这个问题
chrome_options.add_argument(“——user-data-dir = ~ / config / google chrome”)
CI代理使用的我的帐户没有必要的权限，有趣的是一切都在根帐户上工作
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
chrome_options = Options()
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--headless')
chrome_options.add_argument('--disable-gpu')
chrome_options.add_argument('--disable-dev-shm-usage')
chrome_options.add_argument('--profile-directory=Default')
chrome_options.add_argument('--user-data-dir=~/.config/google-chrome')
driver = webdriver.Chrome(options=chrome_options)
url = 'https://www.google.com'
driver.get(url)
get_url = driver.current_url
print(get_url)
