Error: While resolving module `react-native-vector-icons/MaterialIcons`, the Haste package `react-native-vector-icons` was found.

After upgrading my react native project and also my react-native-vector-icons I started receiving this error.

error: bundling failed: Error: While resolving module `react-native-vector-icons/MaterialIcons`, the Haste package `react-native-vector-icons` was found. However the module `MaterialIcons` could not be found within the package. Indeed, none of these files exist:

 * `/Users/user/my-app/node_modules/react-native/local-cli/core/__fixtures__/files/MaterialIcons(.native||.ios.js|.native.js|.js|.ios.json|.native.json|.json)`
  * `/Users/user/my-app/node_modules/react-native/local-cli/core/__fixtures__/files/MaterialIcons/index(.native||.ios.js|.native.js|.js|.ios.json|.native.json|.json)`

The same issue happens with Font Awesome

Module	Version
React-Native	0.52.0
React	16.2.0
React-native-vector-icons	4.5.0

The file it is trying to find does in fact declare that module.

This is why it breaks now: https://github.com/facebook/metro/issues/139#issuecomment-366213751

The broken file: https://github.com/facebook/react-native/blob/master/local-cli/core/__fixtures__/files/package.json

Workaround rm ./node_modules/react-native/local-cli/core/__fixtures__/files/package.json restart packager

• There are some answers below for how to automate this
  • Using rn-cli.config.js
  • Using package.json

I added this to package.json using RN v0.52

"scripts": {
    "postinstall": "rm ./node_modules/react-native/local-cli/core/__fixtures__/files/package.json”
}
