Running into 'Cannot read property 'ReactCurrentOwner' of undefined' after installing packages

Question

I run into the following error in ReactNative on app launch:

Cannot read property 'ReactCurrentOwner' of undefined

This usually happens after installing a new package or switching branches on my project with different sets of packages installed.

I'm can resolve it by running react-native-git-upgrade but this does not seem like a real solution.

Any ideas what can cause this error and how to avoid it?

was having the same issue and as you say, it's a version compatibility problem in react and react-native. Would also affect expo if you're using that.

React + React-native have to use specific versions that work with each other.

The react-community org on Github provides a table that helped me install the correct versions. Here are a few examples from that document:

• [email protected] and 0.42.x need [email protected]

• [email protected] and 0.44.x need [email protected]

• react-native higher than 0.44 to 0.48 need [email protected]

Note that I did npm install --save react@<correct version>

Then rm -rf node_modules && npm install

And lastly: npm start --reset-cache

My app runs again!
