Question: Yarn start Failed with "Error: Unable to resolve module `react-redux`"

Environment node: v13.8.0 yarn: 1.22.0 npm: 6.13.7 mac: mojave

There has an error when build from source:

error: Error: Unable to resolve module react-redux from src/init.tsx: react-redux could not be found within the project or in these directories: node_modules

If you are sure the module exists, try these steps:

1. Clear watchman watches: watchman watch-del-all
2. Delete node_modules: rm -rf node_modules and run yarn install
3. Reset Metro’s cache: yarn start --reset-cache
4. Remove the cache: rm -rf /tmp/metro-*

I reinstall node\yarn\npm, can’t resolve it. Please Help…
