There are a number of different caches associated with your project that can prevent your project from running as intended. Clearing a cache sometimes can help you work around issues related to stale or corrupt data and is often useful when troubleshooting and debugging.

To clear the various caches, run:

Expo CLI and Yarn

Terminal

# With Yarn workspaces, you may need to delete node_modules in each workspace

- rm -rf node_modules

- yarn cache clean

- yarn

- watchman watch-del-all

- rm -fr $TMPDIR/haste-map-*

- rm -rf $TMPDIR/metro-cache

- npx expo start --clear

Expo CLI and npm

Terminal

- rm -rf node_modules

- npm cache clean --force

- npm install

- watchman watch-del-all

- rm -fr $TMPDIR/haste-map-*

- rm -rf $TMPDIR/metro-cache

- npx expo start --clear

React Native CLI and Yarn

Terminal

# With Yarn workspaces, you may need to delete node_modules in each workspace

- rm -rf node_modules

- yarn cache clean

- yarn

- watchman watch-del-all

- rm -fr $TMPDIR/haste-map-*

- rm -rf $TMPDIR/metro-cache

- yarn start -- --reset-cache

React Native CLI and npm
