Answer 1

Install nodemon as globally first, using these commands

`npm install -g nodemon` or `sudo npm install -g nodemon`

Next, ensure the "scripts" field of package.json file as this type

"scripts": {
    "start":"nodemon index.js",
    "devStart": "nodemon index.js"
}

If not as this type then change it and run npm run devStart
