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:
rm -rf node_modules # With Yarn workspaces, you may need to
# delete node_modules in each workspace
yarn cache clean
yarn
watchman watch-del-all
rm -fr $TMPDIR/haste-map-*
rm -rf $TMPDIR/metro-cache
expo start --clear
rm -rf node_modules
npm cache clean --force
npm install
watchman watch-del-all
rm -fr $TMPDIR/haste-map-*
rm -rf $TMPDIR/metro-cache
expo start --clear
rm -rf node_modules # With Yarn workspaces, you may need to
# delete node_modules in each workspace
yarn cache clean
yarn
watchman watch-del-all
rm -fr $TMPDIR/haste-map-*
rm -rf $TMPDIR/metro-cache
yarn start -- --reset-cache
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
