React Native : target with hash string 'android-X' not found

Question

I am trying to develop my first react-native Android app. When I run

sudo react-native run-android

I get the following error

Answer 1

None of the above solutions worked for me, working on a react native app generated with Ignite. Finally, I opened the project up in Android Studio, instead of doing everything via the command line, and a bunch of errors popped up. Fixing the errors one by one within Android Studio solved this problem for me.

You do need the correct path set for ANDROID_HOME for this to work. I installed android sdk with brew, so my path was /usr/local/opt/android-sdk.
