React-native: 0.45.0-rc2: Packager can not find entry file index.ios.js in any of the roots...

[D1no]

When I run a fresh react native project I get the following error. I already changed node version from 6.10 to 7.8. Maybe this has something to do with the latest rc2 update (found under releases) ? Another rc2 project a few days ago ran without any problems.

Reproducing bugs

run
react-native init rn45rc2 --version 0.45.0-rc.2
go into the test project
cd rn45rc2
run i.e. iOS version
react-native run-ios

Possible hint for Solution Aproach

When I run the packenger in another terminal first from the root folder via
npm run start
and than
react-native run-ios

The problem goes away. Still, react-native run-ios seems not to start the packager properly.

I too was banging my head with this most of yesterday...

I wonder will 0.44.4 be available via npm anytime soon?

Only up to 0.44.2 is available.

npm show react-native versions --json

I can see 0.45.0-rc.2, but I can't get it to work.

Also having this issue with the newly released 0.45.0, starting the packager manually does seem to be a workaround but it's far from ideal.

Same problem upgrading from 0.44.2 to 0.45.0

[ethanyanjiali]

Same problem. react-native run-ios is broken on 0.45.0. need to start the packager by npm start

[azmigit]

i have same problem how to fix it

[mrgoonie]

Still the same on 0.46.0-rc.0 (released a few hours ago)

[ethanyanjiali]

I just deleted the app on my simulator and ran react-native run-ios again. it's now working. I've also cleaned all the cache:
watchman watch-del-all
rm -rf node_modules && npm install
npm start -- --reset-cache
not sure if it's related

[azmigit]

[flocbit]

Hi there!

The packager no longer lives in this repo. It now lives in https://github.com/facebook/metro-bundler. The reasoning for the split is explained here: https://github.com/facebook/react-native/issues/13976.

If you're still interested in pursuing this issue, please open an issue on that repo! :)

Thanks!
