Error: While trying to resolve module react-native-vector-icons

[thatjuan]

After upgrading to 4.5.0 recently, I've been getting this error on startup:

error: bundling failed: Error: While trying to resolve module `react-native-vector-icons` from file `/Users/user/Documents/Dev/TestProject/TestProject-RN/TestProject/src/components/Generic/GPIcon.js`, the package `/Users/user/Documents/Dev/TestProject/TestProject-RN/TestProject/node_modules/react-native/local-cli/core/__fixtures__/files/package.json` was successfully found. However, this package itself specifies a `main` module field that could not be resolved (`/Users/user/Documents/Dev/TestProject/TestProject-RN/TestProject/node_modules/react-native/local-cli/core/__fixtures__/files/index.js`. Indeed, none of these files exist:

The only way I've found to get around this is to:

rm ./node_modules/react-native/local-cli/core/__fixtures__/files/package.json

I'm using yarn and I've tried deleting all of node_modules and reinstalling again.

Are you using React Native >=0.52.0? It seems the updated metro profiler is causing some trouble with dependencies that rely on adding custom assets. I'm currently staying at 0.51.0 until it all gets sorted out.

I did this as a workaround.
