Hubot is not responding to hubot help and ping (Win 7 - 32 bit)

I attempted to install and run hubot based following this Tutorial as following:

1. npm install hubot
2. cd node_modules / hubot
3. node node_modules / coffee-script / bin / coffee bin / hubot

Hubot does not respond to any of sample command (help & ping). I managed to solve deprecated issue by modifying robot.coffee code line 283

#app.use express.bodyParser()
app.use express.urlencoded()
app.use express.json()

But the result is the same.

Port 8080 is not in use. Any other ways to resolve/troubleshoot?
