React native init android,ios and app folder missing

Probably you created your project using create-react-native-app, which is an even more simplified toolchain.

You should probably eject if you need android/ios native configs or something.

Please take a look at this doc: https://github.com/react-community/create-react-native-app/blob/master/EJECTING.md

Try this to generate the Android and iOS folder without change version

react-native eject

react-native link

Install a new file using powershell instead of cmd.

Run following commands

1. npx react-native eject

After running above command you can see output in console as follows

info Generating the iOS folder.

info Generating the Android folder.

Next below command

2. npx react-native run-android

npm run eject

next we will get some couple of questions,

? how would you like to eject from create-react-native-app
React-Native : I'd like a regular react native project
? What should your app appear as on a users's home screen? _Your wish____
? What should your Android Studio and Xcode projects be called? rncourse

After Ejected Successfully the project structure will change, added folders android and ios.

happy coding
