Description

I followed instructions when setting up sass but after did the last step I get error in the title

these are scripts in json package

“scripts”: { “build-css”: “node-sass src/ -o src/”, “watch-css”: “npm run build-css && node-sass src/ -o src/ --watch --recursive”, “start-js”: “react-scripts start”, “start”: “npm-run-all -p watch-css start-js”, “build”: “npm run build-css && react-scripts build”, “test”: “react-scripts test --env=jsdom”, “eject”: “react-scripts eject” },

Expected behavior

If it was normal it would start the server and it would compile sass files

Actual behavior

In cli it should run script normally but I get error ‘react-scripts’ is not recognized as an internal or external command, operable program or batch file.’

‘react-scripts’ is not recognized as an internal or external command, operable program or batch file.

Environment

Run these commands in the project folder and fill in their results:

1. npm ls react-scripts (if you haven’t ejected): `–(empty)
2. node -v: v7.0.0
3. npm -v: v3.10.8

Then, specify:

1. Operating system: Windows_NT 10.0.14393

Could it be that your node_modules is corrupted? Can you run npm install and try again?

If it doesn’t work please post the complete output again.

On this machine, I cloned the repo and attempted to run npm start.

It is not enough to run npm start. You need to run npm install to get the dependencies to your machine first. This is not unique to Create React App—it’s just how JS apps generally work in Node/npm ecosystem.

package.json specifies the dependencies but doesn’t actually include the source code for them (sometimes they’re pretty large). So you need to run npm install in the project folder after cloning. After that, other commands will work too.
