npm start error with create-react-app

Question

I have a project who I didn\'t touch for 2 weeks. I take it back and now when I try to run npm start I got this error.

> react-scripts start

You absolutely should not be installing react-scripts globally.
You also don't need ./node_modules/react-scripts/bin/ in package.json as this answer implies.

If you see this:

npm ERR! UpScore@0.6.0 start: `react-scripts start`
npm ERR! spawn ENOENT

It just means something went wrong when dependencies were installed the first time.

I suggest doing these three steps:

1. npm install -g npm@latest to update npm because it is sometimes buggy.
2. rm -rf node_modules to remove the existing modules.
3. npm install to re-install the project dependencies.

This should fix the problem.
If it doesn't, please file an issue with a link to your project and versions of Node and npm.
