I can't get react up and running. When i type npm start then it gives me an error

Question

As you can see i get this error. Has it something to do with my package.json? Default looks like this.

{
    "name": "reactproject",
    "version": "0.1.0",
    "private": true,
    "dependencies": {
        "react": "^16.12.0",
        "react-dom": "^16.12.0",
        "react-scripts": "3.3.0"
    }
}

npm ERR! missing script: start

npm ERR! A complete log of this run can be found in:

PS C:\Users\k12\reactproject> ^C

After i did the command npm rm -g create-react-app i get the following in the command prompt

The error is because you have no start script defined in your package.json

As I don't know what your server set up is, I cannot say what is should be exactly. But something along the lines of:

"scripts": {
    "start": "node index.js",
}

Looking at your package.json, your project seems to be a Create React App project without a template. This occurs when you have an older, globally installed CRA on your machine. The default template package.json should look like this:

{
  "name": "test3",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "@testing-library/jest-dom": "^4.2.4",
    "@testing-library/react": "^9.3.2",
    "@testing-library/user-event": "^7.1.2",
    "react": "^16.12.0",
    "react-dom": "^16.12.0",
    "react-scripts": "3.3.0"
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },
  "eslintConfig": {
    "extends": "react-app"
  },
  "browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }
}

Remove the globally installed version (npm rm -g create-react-app) and try again with npx create-react-app reactproject

See the https://create-react-app.dev/docs/getting-started guide for more information.

Yes i did that. I created my project with the following. – Dec 31 '19 at 00:20
Be sure that you don't have a globally installed CRA on your computer (`npm rm -g create-react-app`) and try again. It should notify you about an older version existing if there is one (A template was not provided) – Pete TNT Dec 31 '19 at 00:23
when i try to start the new folder the command prompt says i use a older version of create-react-app and therefor no template could be created. – Dec 31 '19 at 00:27
See the comment and updated answer: you must remove the older version first with `npm rm -g create-react-app`. After that try running the command again. If the issue persists then you probably have yet another copy of the create-react-app on your machine. – Pete TNT Dec 31 '19 at 00:30
I did what you said. The problem presist. What to do from here? – Dec 31 '19 at 00:39
