i have an iphone and i don't have a macbook so i have to use an emulator android to test my application react-native

When I type the command : react-native run-android

I got 2 errors:

Error #1 :

My emulator is open :

So in android studio i have the same path : Android studio path

And my path is in environment variables : Environnement variables path
