[Error] Error: Unknown error: not all success patterns were matched. It means that "react-native run-android" command failed. Please, check the View -> Toggle Output -> React Native, View -> Toggle Output -> React Native: Run android output windows.
解決的辦法是啟動模擬器，默認是安裝到模擬器上的，我插了手機，只是沒有被識別到。
后來把手機的usb調試打開后，也可以成功的把應用安裝到手機上調試了。
