[RN 0.52.0] Unknown named module: 'react'

[mobdim]

Hello.

After upgrade react-native (0.52.0) I receive this error: Unknown named module: 'react'

Steps to Reproduce

• Create new proj via react-native init
• Install this plugin
• Important! Change file App.js:

const App = () => (
  <View style={styles.container}>
        <Text style={styles.welcome}>
          Welcome to React Native!
        </Text>
        <Text style={styles.instructions}>
          To get started, edit App.js
        </Text>
        <Text style={styles.instructions}>
          {instructions}
        </Text>
      </View>
)

export default App

Just run react-native run-ios

Did you try to reset the cache and restart the packager? Something like this:

rm -rf node_modules/
yarn install
watchman watch-del-all
rm -rf $TMPDIR/react-*

and restart the packager.

@bvic23 Yes, I've tried everything:

watchman watch-del-all
rm -rf $TMPDIR/react-*
rm -rf node_modules/
rm yarn.lock
rm package-lock.json
npm cache clean --force
yarn cache clean
yarn install

And restart

watchman watch-del-all && npm start -- --reset-cache

The only problem on RN 0.52.0 if you use RN 0.51.0, then everything is fine.

I see :-(. Let me look into it and @mobdim feel free to send a PR if you find the solution earlier.

Same issue here. Also on RN 0.52.0.

Also have this issue. It comes from metro bundler I think.

"If you have any scripts in your project that depend on metro-bundler, you will need to change those to metro (related commit). A likely place for this is in rn-cli.config.js.

A new version is now available that should close this
It was fixed in #10

Thanks to @Gyran!

Are you using Yarn? sure the latest version is downloaded?

@Gyran everything worked after I ran react-native start --reset-cache :) Thank you for the fix.

@Gyran @hbarylskyi thanks for much!
I ran react-native start --reset-cache and fixed hot reload on react native version 0.54
