npm start 错误与 create-react-app

npm start error with create-react-app(npm start 错误与 create-react-app)

问题描述

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

sh: react-scripts: command not found

I try to clone my repos too and get the same error. If someone can give me some way to find what happen. Thank you

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.
