Crash on AppCenter build, but not local #51

Closed djMax closed 4 years ago

djMax commented 4 years ago

Somewhat new to RN, but not new to JS or iOS. So, I can run locally in sim and on device in Debug or Release xcode schemes. But when I run from an AppCenter distribution, I get this exception:

*** Terminating app due to uncaught exception 'RCTFatalException: Unhandled JS Exception: Invariant Violation: Tried to register two views with the same name RNCAppearanceProvider', reason: 'Unhandled JS Exception: Invariant Violation: Tried to register two views with the same name RNCAppearanceProvider, stack:

I haven't the foggiest idea where to begin...

I don't know precisely the fix yet, but I do know this is caused by two copies of react-nativea-appearance. I am using a monorepo, which is bleeding edge for RN it seems. So I was using yarn in the root, but then AppCenter was using npm in the RN app directory (blow up part 1). I fixed that, but then AppCenter can't find the react-native-cli, and their build step is not configurable. So I haven't solved that yet. But I think it's fair to say it has little to do with react-native-appearance.
