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)

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!
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()
.usingDriverExecutable(new File(filePath))
.build();
ChromeOptions options = new ChromeOptions();
options.addArguments("--no-sandbox"); // Bypass OS security model, MUST BE THE VERY FIRST OPTION
options.addArguments("--headless");
options.setExperimentalOption("useAutomationExtension", false);
options.addArguments("start-maximized"); // open Browser in maximized mode
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.merge(capabilities);
this.driver = new ChromeDriver(service, options);
}
}
GoogleSearchPageTraditionalSeleniumTests.java
@RunWith(SpringRunner.class)
@SpringBootTest
public class GoogleSearchPageTraditionalSeleniumTests extends BaseSeleniumTests {
@Test
public void getSearchPage() {
this.driver.get("https://www.google.com");
WebElement element = this.driver.findElement(By.name("q"));
assertNotNull(element);
}

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”)
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
以我为例，在以下环境中:
Windows 10 Python 3.7.5 谷歌Chrome 80版本及对应的ChromeDriver路径为“C:\Windows” 硒3.141.0
我需要将参数——no-sandbox和——remote-debug -port=9222添加到ChromeOptions对象中，并以管理员用户身份运行Powershell/cmd来运行代码。
下面是相关的代码段:
options = webdriver.ChromeOptions()
options.add_argument('headless')
options.add_argument('--disable-infobars')
options.add_argument('--disable-dev-shm-usage')
options.add_argument('--no-sandbox')
options.add_argument('--remote-debugging-port=9222')
driver = webdriver.Chrome(options=options)
