Using require() and import for private npm modules failing - node.js

Question

I was trying import my private npm module hosted in sinopia. I can see that my module is available in sinopia folder structure.
Able to install module via "npm install --save". I can see it picks it from local registry.
But when I to use it anywhere I am getting "Error: Cannot find module ''
var module = require('some-module');
(tried both)
import module from 'some-module';
ERROR in ./app/index.js
Module not found: Error: Cannot resolve 'file' or 'directory' ../node_modules/test-module in c:\yotest\app
# ./app/index.js 39:34-77
P.S: I did try installing it as a global node module and it again failed.
EDIT:
This is my package.json of the private module which is a clone from the github project.

Answer 1

I have reconfigured my NPM private registry and there was a port mismatch which was causing the problem.
