我正在尝试在 oracle linux server release 7.6 中运行我的套件，当我尝试同时使用 chrome 和 headless chrom 运行时，服务器中还安装了 chrome 76，每次都会出现以下错误。

即使我在命中和试用的基础上尝试从 chrome 246 驱动程序到 chrome 79 驱动程序，但没有运气

我在这里使用的代码：

} else if (Browser.equalsIgnoreCase("chrome")) {
            System.out.println("Chrome is Starting");
            String chromedriverPath = PropertyfileConfig.getStringValueFromProperty("chromedriverpath");

            System.setProperty("webdriver.chrome.driver", chromedriverPath);

            DesiredCapabilities capabilities = DesiredCapabilities.chrome();
            ChromeOptions options = new ChromeOptions();
            options.addArguments("test-type");
            options.addArguments("--no-sandbox");
            options.addArguments("--disable-dev-shm-usage");
            capabilities.setCapability("chrome.binary", "<Path to binary>");
            capabilities.setCapability(ChromeOptions.CAPABILITY, options);
            driver = new ChromeDriver();
            driver.manage().window().maximize();
            driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);
            //driver.manage().timeouts().pageLoadTimeout(40, TimeUnit.SECONDS);

            System.out.println("Chrome driver selected");
            driver.get(Url);

        } else if (Browser.equalsIgnoreCase("headless")) {

            String chromedriverPath = PropertyfileConfig.getStringValueFromProperty("chromedriverpath");
            System.setProperty("webdriver.chrome.driver", chromedriverPath);

            ChromeOptions options = new ChromeOptions();
            options.addArguments("--no-sandbox");
            options.addArguments("--disable-dev-shm-usage");
            options.addArguments("--disable-gpu");
            options.addArguments("--disable-extensions");
            options.setExperimentalOption("useAutomationExtension", false);
            options.addArguments("--proxy-server='direct://'");
            options.addArguments("--proxy-bypass-list=*");
            options.addArguments("--start-maximized");
            options.addArguments("--headless");

            driver = new ChromeDriver(options);
            driver.manage().window().maximize();
            driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);

            driver.get(Url);

此错误消息...

org.openqa.selenium.WebDriverException: unknown error: DevToolsActivePort file doesn't exist
Build info: version: 'unknown', revision: 'unknown', time: 'unknown'
System info: host: 'arusprint02', ip: '100.104.104.102', os.name: 'Linux', os.arch: 'amd64', os.version: '4.14.35-1902.3.1.el7uek.x86_64', java.version: '1.8.0_222'
Driver info: driver.version: ChromeDriver

...意味着ChromeDriver无法与Selenium语言绑定进行通信。

您的主要问题是您使用的二进制文件版本之间的不兼容，如下所示：

  • 错误跟踪日志中不清楚您的chromedriver版本。
  • 您的chrome= 75.0版本从错误跟踪日志中不清楚。
  • 无法识别您的Selenium 客户端 版本。

所以Selenium Client、ChromeDriver和Chrome 浏览器之间存在明显的不匹配

解决方案

确保这件事：
