React 16 - Incorrect Peer Dependency

Question

After migrating to React 16 I got a lot of warnings which say that there is an incorrect Peer Dependency.

How can I avoid these with yarn?

I tried removing all packages, removed yarn.lock, and added yarn again.

Answer 1

Run 'yarn upgrade'. It should resolve many of the incorrect dependencies. Then you should change versions of the rest packages to the appropriate ones, but expect some packages to be out of date.
