Metro: [BUG] error: bundling: NotFoundError: Cannot find entry file index.ios.js in any of the roots

[mrgoonie]

When I run the react native app on the simulator by react-native run-ios, this error appear:

error: bundling: NotFoundError: Cannot find entry file index.ios.js in any of the roots: ["/Users/goon/HelloRN/node_modules/react-native/packager"]

Bundling `index.ios.js`  0.0% (0/1), failed.

What I've tried:

watchman watch-del-all
rm -rf node_modules && npm install
npm start -- --reset-cache

then
react-native run-ios

..even tried to re-install react & react native

But it's still not working.

@cpojer Looks like an issue to me. react-native run-ios doesn't work after upgrade. Please see issue https://github.com/facebook/react-native/issues/14314 as well.

That's funny when @skevy told us to open the issue over here (ref: https://github.com/facebook/react-native/issues/14314), but then @cpojer close my issue and told me to open it... somewhere else??

@mrgoonie seems to be working fine with react-native 0.45.1 version

Got the same problem after update from react-native 16.0.0-alpha.6 to 16.0.0-alpha.12
with react-native 0.45.0.
After update to 0.45.1 it's working. thanns @switchpt

It was a regression that was fixed in 0.45.1. For reference, here's the commit that fixes it: https://github.com/facebook/react-native/commit/39e0750223a46ba39f7f22f5d8a49f5aca33e378

I have the same error with react-native 0.46.1 and also 0.47.1 on Windows (created with create-react-native-app).
