Ionic info does not work under Windows 7

when I type in the ionic info command in my project folder in the command shell on Windows 7 it just hangs forever and does not print anything.

c:\project\photo-gallery>ionic info
Batchvorgang abbrechen (J/N)?
c:\project\photo-gallery>ionic --version

I haven’t found any hint on the net. Seems no one had this problem before.

Thanks for any help.
