Can't switch node version

Hi

I am trying to change my node version to use with ionic. But I can’t !

It’s the second time I’ve run into troubles with ionic/nvm…this should be working ‘out of the box’ really…

$ nvm ls
 v0.10.33
 v0.12.7
 ->    system
 default -> 0.12 (-> v0.12.7)
 stable -> 0.12 (-> v0.12.7) (default)
$ nvm alias default 0.12
 default -> 0.12 (-> v0.12.7)
$ node --version
 v0.10.25

Can you please help me switch to 0.12 and make it persist ?

Thanks
