issues while creating custom react-scripts

[shrynx]

Description

I am making a custom react-scripts, and i used the latest master branch to clone and modify it. but while running i get into error Cannot find module 'react-dev-utils/getProcessForPort'

Expected behavior

The master branch of create react app has the getProcessForPort.js, but the one downloaded from npm doesn't have it. (probably not part of the release ?)

Reproducible Demo

to reproduce this i have published the broken package on npm
create-react-app myApp --scripts-version super-react-scripts

Yes, you'd either need to wait for the next react-dev-utils release, rollback your fork to before it was changed, or fork it too.

I’ll close because this is not very actionable for us. This particular issue will be solved with next release, but in general it might be better to fork from the latest stable version rather than from master.

@shrynx In my fork I just copied the file that was missing.

Of course, this is temporary until the new version of react-dev-utils is published.

@kitze Oh alright, i just commented out the code. Although, I will be copying a few things from your fork :)

@shrynx one advice, if you want to keep up with the original repo easily, don't modify too many things otherwise you'll have a headache. I'm modifying only ~10 lines and it's still hard 😅

[shrynx]

@kitze Thanks for the advice. I currently have modified code to a decent extent, but i saw your repo. Will try to approach similar way.

@shrynx cool 👍

Btw this already exists in the original CRA, you can achieve it by adding PORT=3000 into .env

@kitze Oh yeah, totally makes sense. I even documented regarding environment variable. must have slipped off from my mind. Thanks for the heads up.
