Unable to use “npm start”

While running ‘npm start’ I am getting the following error message:

 internal/modules/cjs/loader.js:582
  throw err;
  ^

Error: Cannot find module 'C:\Users\cheny\workspace\VisualStudioCode\pluralsight-js-dev-env\buildScript\srcServer.js'

This is my package.json

node version is 10.14.1 npm version is 6.4.1

I manage to find similar issues while searching in the web but still I can’t figure it out what is the problem ??

I tried so many things like delete , reinstall ,npm install etc.

This is very frustrating. I am new to node so I guess its something small but I have no idea what.

Any advice will be appreciate

Thank you
