Im also getting this error but ok.
solution: rm -rf /tmp/metro-bundler-cache-*
@nicoara I ran this script I have to clear all my caches.
$ echo 'Delete Watchman' && watchman watch-del-all && echo 'Clear RN packager cache' && rm -rf $TMPDIR/react-native-packager-cache-* && echo 'Clear Metro cache' && rm -rf $TMPDIR/metro-bundler-cache-* && echo 'Clear Haste Map cache' && rm -rf $TMPDIR/haste-map-react-native-packager-*
I get the same error. So your solution isn't a one-size-fits-all unfortunately.
