Cannot find module react-scripts

Question

In package.json file I have these scripts:

"scripts": {
    "server": "json-server --watch db.json --port 5000",
    "client": "npm start --prefix client",
    "client-build": "npm run-script build --prefix client",
    "chat": "nodemon index.js",
    "dev": "concurrently \"npm run server\" \"npm run client\"",
    "build": "concurrently \"npm run server\" \"npm run client-build\" \"npm run client\""
  },

And I use the "npm run dev" command to run server and client at the same time. The server runs, but an error occurs with the client:

react-scripts start

I cleared the npm cache, deleted and reinstalled the node_modules folder, even installed the react-scripts package separately, but none of it worked.

Answer 1

There is several solution to start your application.

1. Run npm run build first, and do npm run start
2. You might need to install the package npm i react-scripts
3. If you are on window machine, replace your capital "i" I in your project path into something different.

Answer 2

you have to go into the node modules folder and rewrite the location of the scripts its strange i had that issue before, im pretty confident thatll fix you up
