after ionic team has officially released ionic 1.2 versions
I checked 

> 
> ionic -v
> 
> 
> 

command to get my current version and I found it 1.7.12, then I did 

> 
> npm install -g ionic
> 
> 
> 

hopefully to update my current version and it just still on the previous version 1.7.12, so what is just the command I have to run to get the ionic 1.2 instead of ionic 1 which I already have now?
