@ multi main (CLI v2.0.0-beta.15)

Your system information:

Cordova CLI: 5.4.1
Ionic Version: 2.0.0-alpha.45
Ionic CLI Version: 2.0.0-beta.15
Ionic App Lib Version: 2.0.0-beta.8
OS:
Node Version: v5.3.0

I also have installed windows phone 8 sdk, should this be the problem?

When I'd installed the node again, the OS: information was gone from the system info too..

Can anyone give me some light in the end of tunnel?

Please Help!
