我正在尝试使用URL启动chrome,浏览器启动,之后它什么都不做.

我在1分钟后看到以下错误:

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:66 ChromeBrowser:2.39.56

PS在Firefox中一切正常

在python-selenium chrome_options中，以下两个选项到底有什么区别，我知道两者都运行selenium脚本而不打开浏览器。

chrome_options.add_argument('--headless')
chrome_options.add_argument('--disable-gpu')

我也有一个带有 UI 的 ubuntu 服务器。你可以通过触发 mvn test 命令来执行测试用例。但问题是当我从另一台机器通过终端对机器执行 ssh 时，我收到以下错误 -

unknown error: DevToolsActivePort file doesn't exist
  (Driver info: chromedriver=2.40.565383 (76257d1ab79276b2d53ee976b2c3e3b9f335cde7),platform=Linux 4.4.0-121-generic x86_64) (WARNING: The server did not provide any stacktrace information)

Driver info: driver.version: ChromeDriver

但是，如果我通过 remmina 远程控制机器，然后执行该机器终端的相同命令，则相同的命令会成功启动 chrome。

线程函数中的Java代码：

    System.setProperty("webdriver.chrome.driver", "/usr/bin/chromedriver");
    ChromeOptions chromeOptions = new ChromeOptions();
    chromeOptions.addArguments("--no-sandbox");
    chromeOptions.addArguments("--user-data-dir="+config.chromeUserDir);
    chromeOptions.addArguments("--profile-directory="+profile);
    chromeOptions.addArguments("--start-maximized");
    WebDriver driver = new ChromeDriver(chromeOptions);
    driver.get("https://www.google.com");

并使用以下代码创建对象并在线程中启动

    Driver d1 = new Driver(profile);
    d1.start();

    Driver d2 = new Driver(profile1);
    d1.start();

已经创建了两个不同的配置文件，代码在单线程下运行良好，但在多线程下它不会在两个单独的窗口中打开谷歌网站。它说，
