Error: Cannot find module 'metro/src/DeltaBundler/Worker'

See original GitHub issue

When I run the react-native start I am getting this error message. I cleaned up all cache and removed node_modules/ these don’t work.

Can anyone help me, please?

My versions are.

react-native -v
react-native-cli: 1.2.0
react-native: 0.57.3

All code block as below;

react-native start --reset-cache

@soranoba didn’t work for me either. @aafarian I think there’s an issue with the version of metro packaged with the latest RN Upgrade. I just installed locally in dev metro npm install --save-dev metro, which is the version 0.51.1, and that worked for me.

FYI: I also encountered the same issue, but I solved it.

rm -rf $TMPDIR/metro-cache*
watchman watch-del-all
react-native start --reset-cache
