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
http://170.210.201.179/linux/chrome/deb/pool/main/g/google-chrome-stable/

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。
我的问题是php-webdriver中的一个bug。我的代码是:
$chromeOptions = new ChromeOptions();
$chromeOptions->addArguments([
'--headless',
'--no-sandbox',
'--disable-gpu',
'--disable-dev-shm-usage',
'--no-proxy-server'
]);
$chromeOptions->setExperimentalOption('detach', true);
$capabilities = DesiredCapabilities::chrome();
$capabilities->setCapability(
ChromeOptions::CAPABILITY,
$chromeOptions
);
如你所见，一切都符合其他可能的原因。
但实际上这些功能并没有传递给chromedriver。我不得不改变设置chrome选项功能:
$capabilities->setCapability(
ChromeOptions::CAPABILITY_W3C, // <<< Have to use W3C capabilities with recent versions of Chromedriver.
$chromeOptions->toArray() // <<<<< bug in php-webdriver 1.9, object not getting serialized automatically like with the deprecated capability ChromeOptions::CAPABILITY
);
我的设置是:
$ chromedriver --version
ChromeDriver 79.0.3945.36 (3582db32b33893869b8c1339e8f4d9ed1816f143-refs/branch-heads/3945@{#614})
$ java -jar selenium-server-standalone-3.141.59.jar --version
Selenium server version: 3.141.59, revision: e82be7d358
做了一个bug报告和一个PR来修复php-webdriver中的这个bug
https://github.com/php-webdriver/php-webdriver/issues/849
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");
对于Ubuntu 20，它确实帮助我使用我的系统铬驱动程序，而不是下载的那个:
# chromium which
/snap/bin/chromium
driver = webdriver.Chrome('/snap/bin/chromium.chromedriver',
options=chrome_options)
对于下载的web驱动程序来说，它看起来需要远程调试端口——remote-debugging-port=9222来设置，就像其中一个答案(由Soheil Pourbafrani):
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument("--remote-debugging-port=9222")
driver = webdriver.Chrome('<path_to>/chromedriver', options=chrome_options)
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:
browser: chrome
capabilities:
extra_capabilities:
chromeOptions:
args:
- "headless"
- "no-sandbox"
- "disable-dev-shm-usage"
