When i try to run my application using expo i have this error : unable to resolve module './fonts/Entypo.ttf' from /home/pfe/node_modules/@expo/vector-icons/Entypo.js'
npm : 4.3.0 react-native-cli: 2.0.1 react-native: 0.42.0 expo@ 15.1.3
I had that issue. Check last comment in https://github.com/expo/vector-icons/issues/8. If that doesn't work, then read all of the comments.
I hope that helps
