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

我最近也面临着同样的问题，经过一些试验和错误，它也适用于我。
必须在最上面:
options.addArguments("--no-sandbox"); //has to be the very first option
BaseSeleniumTests.java
public abstract class BaseSeleniumTests {
private static final String CHROMEDRIVER_EXE = "chromedriver.exe";
private static final String IEDRIVER_EXE = "IEDriverServer.exe";
private static final String FFDRIVER_EXE = "geckodriver.exe";
protected WebDriver driver;
@Before
public void setUp() {
loadChromeDriver();
}
@After
public void tearDown() {
if (driver != null) {
driver.close();
driver.quit();
}
}
private void loadChromeDriver() {
ClassLoader classLoader = getClass().getClassLoader();
String filePath = classLoader.getResource(CHROMEDRIVER_EXE).getFile();
DesiredCapabilities capabilities = DesiredCapabilities.chrome();
ChromeDriverService service = new ChromeDriverService.Builder()

其他回答
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.)
Build info: version: '3.141.59', revision: 'e82be7d358', time: '2018-11-14T08:17:03'
System info: host: 's1n7ax', ip: '127.0.1.16', os.name: 'Linux', os.arch: 'amd64', os.version: '5.4.70-1-lts', java.version: '11.0.8'
Driver info: driver.version: ChromeDriver
remote stacktrace: #0 0x56030c96dd99 <unknown>
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

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
在我的例子中，我在Kubernetes环境中不能使用默认的TMPDIR，因为它会用垃圾填满临时目录。
所以我用这个来使用不同的tmpdir:
driver = new ChromeDriver(new ChromeDriverService.Builder()
.withEnvironment(ImmutableMap.of("TMPDIR", customTmpPath))
.build(), options);
但现在我把所有东西都升级到最新版本，这似乎不再管用了。我需要找到一种新的方法来做这件事。
