Node.js CLI error or How to trigger script from command line for LoadRunner Cloud?

Hi everyone! 

I am looking to trigger LoadRunner Cloud script from command line (Windows). 

I have tried to install Node.js CLI tool from here  

But I am getting error when running "npm install" as mentioned in steps in the link above.

I am not behind proxy (npm config get proxy // returns null) and connected to internet, can access any other websites except fraartifactory one. 

I understand that it is trying to reach this website since it is mentioned in package.json file. But since it is giving DNS error, what website should it reach to? 

How to resolve these errors? Is there any other way to trigger a script from cmd?

Any advice or help highly appreciated! Thanks!
