hi, i have a big problem with ionic. I cannot create a new project. when I type:
ionic start myApp tabs, I have this answer:
C:\Users\USER\Desktop\application>ionic start myApp tabs

Pick a framework!

Please select the JavaScript framework to use for your new app. To bypass this prompt next time, supply a value for the
–type option.

? Framework: Angular
? .\myApp exists. Overwrite? Yes
√ Preparing directory .\myApp - done!
√ Downloading and extracting tabs starter - done!
