On installing react-native-search-header gives me an error , several files provide this module, delete or fix them.

Can you post your package.json?
I have the same issue.
It would help me track down the issue if you could post your package.json "dependencies".
I think, the reason is our apps uses "react-native": "0.49.5". I have same error btw.
I looked this issue in react native github issues and one person suggested the following...
remove both react-native-packager-cache-* (directory) AND haste-map-react-native-packager-* (file) from $TMPDIR
@kmtilwani @belltolls @artemukolov I have fixed the issue by updating the package's dependencies. The fix is live if you want to refer to this git repo for rn-search-header in your package.json like so: "react-native-search-header": "github:tuantle/react-native-search-header",
I also just submitted a PR for a version bump, so 0.2.4 should have the fix when @tuantle accepts it
