Initially it wasn't ablel to find a module, so I reverted back my code , and now I see that The simulator works, , but still it says that Build Failed, what is that ? Please guide.

remove the node_modules and install them again.
You are using old libs..

rm -rf node_modules
npm i

Solved the problem for me..

@Stoffern solution didnt worked for me but like he says, i´ve been using old libs, so after upgrading RN it worked. I did react-native-git-upgrade (react-native upgrade) and now it uses v0.44

Reinstalling the node modules worked for me. Thanks @Stoffern!
