I'm currently trying to get the ES6 react-native-webpack-server running
on an Android emulator. The difference is I've upgraded my
i just upgraded to react-native
0.18.1 today tough having some peer dependencies issues with
0.19.0-rc pre-release version.
Back to your question, what I did was
sudo ./gradlew clean
then back to the working directory and run
you should restart your npm too after that upgrade.
hope this works for you.
