After updating to 0.6.0, Error: Cannot find module 'react-dev-utils/webpackHotDevClient'

It seems create-react-app is updating very frequently right now, but there’s no guidance in how to keep an app you created with create-react-app up to date. It seems one way may be to update react-scripts via something like:

npm install --save-dev react-scripts@latest

But without any official documentation, it’s not clear if this is entirely sufficient. I just tried doing that from 0.5.1 to 0.6.0 and I got an error:

pbeshai: ~/Workspace/my-project $ npm start

> my-project@0.1.0 start /Users/pbeshai/Workspace/my-project
> react-scripts start

module.js:442
    throw err;
    ^

This error is resolved by running:

npm install --save-dev react-dev-utils

but there’s no guidance in how to keep an app you created with create-react-app up to date.

Isn’t it the very first section in the User Guide? It’s linked from main README, too.

Yes, of course. If you have problems please file a new issue with instructions to reproduce.

Note that if you’re using npm 5 you’re probably hitting one of its many bugs. Please try downgrading to npm 4 in the meantime. npm install -g npm@4
