Unable to add plugins. Perhaps your version of Cordova is too old. Try updating
(npm install -g cordova), removing this project folder, and trying again: (CLI v
2.0.0-beta.15)

Your system information:

Cordova CLI: 5.4.1
Gulp version:  CLI version 3.9.0
Gulp local:
Ionic Version: 1.2.1
Ionic CLI Version: 2.0.0-beta.15

OS: Windows 7
Node Version: v5.3.0

Getting

Couldn't find ionic.project file. Are you in an Ionic project? (CLI v2.0.0-beta.15)

In the folder that gets created i see no plugins folder and ionic.project file

the same happens with
ionic start cutePuppyPics1 --v1 command

can you let me know??
