I am having the same issue and none of the options work Unable to resolve module uuid from /Users/pranav.dixit/react_navtive_projects/AppUpdate/node_modules/react-native/Libraries/Blob/Blob.js: Module does not exist in the module map

This might be related to https://github.com/facebook/react-native/issues/4968 To resolve try the following:

Clear watchman watches: watchman watch-del-all.
Delete the node_modules folder: rm -rf node_modules && npm install.
Reset Metro Bundler cache: rm -rf $TMPDIR/react-* or npm start -- --reset-cache. 4. Remove haste cache: rm -rf $TMPDIR/haste-map-react-native-packager-*.

Hi! I am experiencing the same issue. When I run npm install, uuid dependency is not found. Using yarn instead of npm is solving this issue. My assumption is that yarn places uuid as a shared dependency at the top of the dependency tree and npm does not do it. If uuid module is used in the blob library, it should b explicitly added to React dependencies.
