Unable to run server on Ubuntu

[sginji]

I see the following error when I run the server on Ubuntu:

$ npm install npm WARN [email protected] No description npm WARN [email protected] No repository field. $ node index.js listening on *:3000 forwarding to global domain... ngrok server: undefined

I am trying to run this behind a lab server but have set proxy settings for Ubuntu as well as for npm. Are there any additional dependencies/settings that need to be taken care of in order to get the server running?
