Where are you running your start command from in your file structure? It seems like you're inside the views directory, tried to run `node app.js` when in fact you need to be one level up. Can you give the print out of where you are in your directory structure, plus what all the files are inside that directory? — Elliot Blackburn, Mar 02 '18 at 10:16

Check your package.json file. It looks like your app.js and the package.json are not in the same folder.

{
  "name": "final-project",
  "version": "1.0.0",
  "description": "",
  "main": "app.js",
  "scripts": {
    "start": "node app.js" // <--- node can't find app.js file
  },
  "keywords": [],
  "author": "",
  "license": "ISC"
}

You must change that to:

"scripts": {
    "start": "./views/app.js" // or wherever app.js file is
}

Thank you but my app.js is not in views it outside. I think json script should find app.js by default when we try to install json package. And they are in same folder. – CopyPaste Mar 02 '18 at 11:45
@CopyPaste What command are you using to run the app? You can see the `Error: Cannot find module 'C:\Users\Haider Ali\Desktop\OLS\OLS\views\app.js`. Node thinks that your app.js is inside the `/views` directory. – Utkarsh Bhatt Mar 02 '18 at 12:43
