How to find cause of Warning: PropTypes has been moved to a separate package

Question

If I get the warning \"Warning: PropTypes has been moved to a separate package.\" How can I locate which npm package is still using it? The warning doesnt offer any details

Answer 1

This is just an idea so might not be that useful or there would be a better solution but you can use npm ls command to get the dependency tree. Then you can locate the packages that depends on react but not prop-types. This is sort of a manual solution and might be a better one.

More info about npm ls here
