A template was not provided. This is likely because you're using an outdated version of create-react-app.
Please note that global installs of create-react-app are no longer supported.

C:\Users\Angengos>cd learn-react/

C:\Users\Angengos\learn-react>npm start
npm ERR! missing script: start

AND THIS IS THE PACKAGE.json

{
  "name": "learn-react",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "react": "^16.13.1",
    "react-dom": "^16.13.1",
    "react-scripts": "3.4.1"
  }
}

AND HERE IS THE NODE AND NPM VERSION

C:\Users\Angengos\learn-react>node --version v12.16.2

C:\Users\Angengos\learn-react>npm --version 6.14.4

Seems the scripts are not in you package json. Add this and yry again:

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

It should look like this:

{
  "name": "learn-react",
  "version": "0.1.0",
  "private": true,
  "scripts": {
      "start": "react-scripts start",
      "build": "react-scripts build",
      "test": "react-scripts test",
      "eject": "react-scripts eject"
},
  "dependencies": {
     "react": "^16.13.1",
    "react-dom": "^16.13.1",
   "react-scripts": "3.4.1"
  }
}
