Appium Inspector失败了

Question

我正在尝试将appium连接到genymotion模拟器。在Appium.app（Mac os x）中，当我单击检查器按钮时，它会抛出如下错误：

  Could not start a new session

        Be sure the Appium server is running with an application opened by
     using the "App Path" parameter in Appium.app (along with package and 
    activity for Android) or by connecting with selenium client and supplying 
    this in the desired capabilities object.
