npm ERR! Missing script: "start"-CodePudding

I'm newbie to react js.Trying to run a simple app and getting this error and can't figure out what's wrong

D:\React app\react-app1>npm start
npm ERR! Missing script: "start"
npm ERR!
npm ERR! Did you mean one of these?
npm ERR!     npm star # Mark your favorite packages
npm ERR!     npm stars # View packages marked as favorites

This is package.json file

{
  "name": "react-app1",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "react": "^18.1.0",
    "react-dom": "^18.1.0",
    "react-scripts": "5.0.1"
  }
}

CodePudding user response：

This happens becaue you have no script called "start" in your package.json file. Here is an example of a package.json file with such script:

{
  "name": "your-project",
  "version": "1.0.0",
  "description": "",
  "main": "main.js",
  "scripts": {
    "start": "node main.js"
  },
  "author": "Muralidharan",
  "dependencies": {
  }
}

CodePudding user response：

add this to your package.json

 "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject",
  },

start is the command you need that trigger react-script to run your project build, test and eject are other command you will need for development process

Thanks to all who answered the question, the issue was with the outdated version So I have done this to resolve

1. npm uninstall -g create-react-app
2. npm install create-react-app  ( v1.5.2 is outdated and no longer supported
