Answer 1

它说你的驱动程序版本未知。可能找不到chrome驱动程序，或者您使用的chromedriver.exe版本与您安装的chrome版本不兼容。

要启动节点，需要告诉jar chromedriver在该机器上的位置。差不多

java -Dwebdriver.chrome.driver="C:\Users\xxxx\Documents\Browsers\ChromeDirectory\chromedriver.exe" -jar selenium-server-standalone-3.8.1.jar -role node -hub "http://xx.xxx.xx.xxx:4444/grid/register/" -nodeConfig config.json

在代码中尝试这样的内容：

if (Utilities.Browser == "Chrome")
    {
        ChromeOptions options = new ChromeOptions();
        options.AddArgument("disable-extension");
        options.AddAdditionalCapability("useAutomationExtension", false);
        if (Utilities.useSeleniumGrid == "true")
            {
                if (headless)
                {
                    options.AddArgument("no-sandbox");
                    options.AddArgument("headless");
                }
                _currentWebDriver = new RemoteWebDriver(new Uri(Utilities.SeleniumHub), options.ToCapabilities(), TimeSpan.FromMinutes(3));
            }
            else
            {
                _currentWebDriver = new ChromeDriver(chromePath, options);
            }
        }
