what is your ionic info

cli packages: (C:\Users\intex\AppData\Roaming\npm\node_modules)

@ionic/cli-utils  : 1.9.2
ionic (Ionic CLI) : 3.9.2

local packages:

@ionic/app-scripts : 2.1.3
Ionic Framework    : ionic-angular 3.6.0

System:

Node : v7.10.0
npm  : 4.2.0
OS   : Windows 7

update you global npm to 4.6.1 and reinstall the node modules. then try again

after updating global npm to version 4.6.1 I am still facing this issue.

What error? I only see 3 warnings. Warnings can be ignored most of the time, as in this case.
