Cant find app folder (Ionic 2 ,Mac)

sudo npm install -g ionic@beta
ionic start mytest --v2 --ts

and then i check the ionic version (ionic -v ) its tell me that my version is : 1.7.8
it seems that i have the older version of ionic

please help :slightly_smiling:

try to install the correct version of ionic.

npm install -g ionic@beta

I did it , still version 1.7.8

oh i see. you said, you’re using npm as sudo. that’s not how that program is supposed to work.
try it without sudo.
