Need to clear development caches on Windows? Find the relevant commands here.

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

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

npm start -- --reset-cache
