Did you mean packages/react-hot-loader/packages.json? The one exposed as react-hot-loader to npm.

Thank you. Sorry about that.

Thanks for it. Just a little problem, this project is using yarn. You have to install it with yarn, to do it just run yarn at the root of the project then go in packages/react-hot-loader and run yarn add prop-types.

Right. I have to include the yarn.lock file too :) Fixed.
Thanks.
