@sharathprabhal , try to close the terminal that opened by the packager, it runs package at port 8081, close it will terminate the packager process, then you re-run react-native run-ios, it should work.

I’m running into this in ^5.0.0. Anyone else having this problem? I’ve tried several different versions of babel-preset-react-native and haven’t had any luck.
