Angular 2 - install on standalone computer - node.js

Question

I'm trying to install Angular 2 on standalone computer.
I tried to install the framework on a computer that connected to the network with the following steps:
1) download the quick start from github.
2) cd to the quickstart-master directory.
3) use npm install.
4) use npm start.
the "Hello Angular" application is running successfully.
After I copied the quickstart folder to the standalone computer (which has node installed) I did the following steps:
1) cd to the quickstart directory.
2) used npm start.
This time when the chrome browser is opened I get "Loading AppComponent content here..." and NOT "Hello Angular".
How can I use Angular 2 on the standalone computer?
thanks a lot!
