strongloops lb-ng fails in windows - angularjs

Question

I am going through the tutorial LoopBack/Getting started part II.
Everything is happening as expected until I come to the "Create AngularJS client".
When I try to execute (Windows 7):
lb-ng server/server.js client/js/services/lb-services.js
following happens:
C:\learn\loopbackLearn>lb-ng server/server.js client/js/services/lb-services.js
Loading LoopBack app "C:\\learn\\loopbackLearn\\server\\server.js"
{ [Error: Cannot find module '../build/Release/bson'] code: 'MODULE_NOT_FOUND' }
js-bson: Failed to load c++ bson extension, using pure JS version
module.js:338
throw err;
^
Error: Cannot find module 'async'

I understand that the fact that the c++ bson extension is missing is just a warning ... but how do I cope with the missing "async" module?
Can you help me?
Thanx!

In Linux, I had to install async manually before proceed.
$ npm install async --save
After this, I got the following error:
Error: ENOENT, no such file or directory '/home/action/workspace/github-nodejs/react/loopback-getting-started/client/js/services/lb-services.js'
I created the directory and after this everything worked ok.
$ mkdir client/js
$ mkdir client/js/services
$ lb-ng server/server.js client/js/services/lb-services.js
