Have you read the Contributing Guidelines?

yes

Environment

Environment: OS: macOS Sierra 10.12.6 Node: 6.9.2 Yarn: Not Found npm: 5.6.0 Watchman: 4.7.0 Xcode: Xcode 9.2 Build version 9C40b Android Studio: 2.3 AI-162.4069837

Packages: (wanted => installed) react: 16.2.0 => 16.2.0 react-native: 0.52.0 => 0.52.0

Steps to Reproduce

1. Install https://github.com/oblador/react-native-vector-icons
2. Use in a component
3. Start app

Expected Behavior

App starts successfully

Actual Behavior

Error is shown:

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)`

Steps to fix

As per https://github.com/oblador/react-native-vector-icons/issues/626

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

It looks like this file is outdated for some time, I’m not sure if it needs to be there but it should either be updated or removed. For some reason it refers directly to the react-native-vector-icons project.

Workaround: addition of rn-cli.config.js (for RN 0.52 at least):

const blacklist = require('metro/src/blacklist')
module.exports = {
  getBlacklistRE () {
    return blacklist([/react-native\/local-cli\/core\/__fixtures__.*/])
  },
}

It seems some blacklist items were lost in the process of moving from RN to metro 😕

@afilp rn-cli.config.js should be located in the root directory of the project. It is location where RN will find it automatically (https://github.com/facebook/react-native/issues/7271). Seems this info not documented.
