Ionic doesnt create correct template

hi guys. im new in ionic.

I try to create new project with sidemenu template.
so i type "ionic start MyProject sidemenu"
but that always makes a blank template for me
also i tried tabs template bud that doesnt work too!
i checked www folder in my project path, there in nothing there for sidemenu template. that doesnt make its css or js file.
