Selenium Chrome 驱动程序 v92：无连接（在 v91 中一切正常）

Question

我已更新到 Chrome v92（新的 chromedriver 92.0.4515.43 已下载并且 chrome 浏览器自动更新到 v92）

但是现在我们的测试在由 jenkins 启动时不再起作用。当我手动开始测试时，一切都在无头模式下工作。

通过jenkins出现以下错误：

org.openqa.selenium.SessionNotCreatedException: Could not start a new session. Response code 500. Message: session not created

这是代码，chrome已初始化

System.setProperty("webdriver.chrome.driver", FilePath + "\\drivers\\chromedriver.exe");
HashMap<String, Object> chromePrefs = new HashMap<String, Object>();
chromePrefs.put("profile.default_content_settings.popups", 0);
chromePrefs.put("download.default_directory", FilePath);
ChromeOptions options = new ChromeOptions();
HashMap<String, Object> chromeOptionsMap = new HashMap<String, Object>();
options.setExperimentalOption("prefs", chromePrefs);
options.addArguments("--disable-notifications");
options.addArguments("--disable-popup-blocking");
options.addArguments("--headless");
options.addArguments("--disable-gpu");
options.setCapability(ChromeOptions.CAPABILITY, chromeOptionsMap);
options.setCapability(CapabilityType.ACCEPT_SSL_CERTS, true);
options.setCapability(ChromeOptions.CAPABILITY, options);
options.setPageLoadStrategy(PageLoadStrategy.NORMAL);
driver = new ChromeDriver(options);

使用 chromedriver v91 安装 Chrome v91 时，一切正常。所以问题与 v92 的更新有关。

有人有想法吗？

有时会出现此错误：

Answer 1

尝试执行您的代码：

options.addArguments("--no-sandbox");
options.addArguments("--disable-dev-shm-usage");

/dev/shm 分区在某些 VM 环境中太小，导致 Chrome 失败或崩溃（请参阅http://crbug.com/715363）。使用此标志来解决此问题（将始终使用临时目录来创建匿名共享内存文件）。

参考：

Answer 2

添加这两行代码对我有用：

options.addArguments("--no-sandbox");

options.addArguments("--disable-extensions");
