Cannot download ionic-app-base with proxy under windows when start new app

Hi all,

I am new and try to create a app using ionic start --v2 blank, but when downloading ionic-app-base it failed with timeout error, like below:

Downloading: https://github.com/driftyco/ionic2-app-base/archive/master.zip
Error with start Error: connect ETIMEDOUT 192.30.253.113:443

npm and git are using the same proxy, and can update/install and clone/push, but it always fail even I set PROXY variable in system by command like below:
set PROXY=ip:port

Can anyone help or is it really a issue?

version as below:

$ ionic -v
2.2.1

Really need your help~~

This is more or less a general npm question.

Thank you mhartington, my npm and git works fine with proxy, only ionic cannot work, any clues about it?

Retried several times and finally succeed with export proxy out under mac.

Thank you~
