Node.js Cannot Find Module error on npm start

Question

I am getting an error like the below when I run npm start command to start the server for my first react project. I have tried uninstalling and reinstalling the node.js but did not work. How can I resolve this issue? I am including my package.json and my directory structure over here.

This is the error:

    > [email protected] start C:\Users\LENOVO\reactproject1
    > node index.js
    
    internal/modules/cjs/loader.js:969
      throw err;
      ^

This is my package.json file of my react project. I have edited it by adding "start":"node index.js".

{
  "name": "reactproject1",
  "version": "1.0.0",
  "description": "restropart",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "start": "node index.js"
  },

  "author": "",
  "license": "ISC",
  "dependencies": {
    "react": "^16.13.1",
    "react-dom": "^16.13.1"
  }
}

My Directory tree is as follows

-ReactProject
  -node_modules
  -public
  -src
    ->index.js
  -package.json
  -package-lock.json

My index.js file resides inside the src folder. The node_modules, public, src, package.json and package-lock.json files are on the same line.

Can you show your project file structure and where is the index.js file located — Shaurya Vardhan Singh

The start script refers to index.js, but you don't have such a file - it's under src/index.js. You could either move it to the project root, or update the start script accordingly:

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