undefined is not an object (evaluating n.reactCurrentOwner

After adding all my necessary npm packages on my app and try to run, I’m en counteracting this bug. I have tried the following and still same bug

watchman watch-del-all
rm -rf ./node_modules
yarn cache clean
rm -rf $TMPDIR/react-*
yarn install
npm start -- --reset-cache

I’ve also tried to update everything to latest version and still same bug. i.e

I’m stuck on this issue too, I’m currently using those versions:

react: 16.0.0-alpha.12
react-native: 0.45.1
npm: 5.0.3
node: v8.1.3
yarn: v0.24.6

I’m experiencing a similar issue issue when trying to add react-native-web to an existing react-native project: Cannot read property 'ReactCurrentOwner' of undefined. react-native-web currently requires react v15.4.x which is a different version than the one installed with the current version of react-native. To fix the issue I had to downgrade react-native to 0.42.3 (which uses react ~15.4.0 as a peer dependency) and set react, react-dom, and react-test-renderer to 15.4.1.

tl;dr make sure the versions of react in your dependencies are matching.
