I have a problem "Unable to resolve module".
// Please, read the question before publish comments with links for first result from google.
This is the import line where I got the error:
import Interactor from 'react-native-native-orientation-interactor';
What I did:
- Create a react-native library
 - Run 
npm linkinside the library folder - Run 
npm link react-native-native-orientation-interactorinside a demo react-native app - Add import statement
 - Got the error with import.
 
If I press Cmd+B on import statement I can open a file from node_modules folder. Also I can see my library (as a link) inside node_modules.
But I didn't find any solution for me.
Upd1: I added my library as a dependency in package.json
  "dependencies": {
    "react": "16.9.0",
    "react-native": "0.61.5",
    "react-native-native-orientation-interactor": "*"
  },
