启动 Inspector 的时候会弹出以下问题，求助攻，

Could not get list of sessions from Appium Server

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.
