我是 Appium 的新手。我想在移动设备上的 Chrome 浏览器中启动站点 (amazon.in)，为此我下载了安装在我的 Win7 机器上的最新 appium-desktop 1.7.0。我启动了在端口 5000 上运行的 Appium 服务器，然后单击了启动检查器部分。在自动服务器选项卡下添加了所需的功能，如下所示

 {
      "udid": "c78cd64b7ce4",
      "browserName": "Browser",
      "platformVersion": "7.1.2",
      "platformName": "Android",
      "noReset": true,
      "automationName": "UiAutomator2",
      "deviceName": "Android"
    }

单击“开始会话”时，其抛出错误为“处理命令时发生未知的服务器端错误。原始错误：命令 'java -version' 以代码 2 退出”

在控制台日志中显示为
