Help with solving the DistributionNotFound error in Virtualenv

I've installed virtualenv on my system which the argument to not copy over any site packages. Then I did an easy_install to install Django and that went fine too.

In the virtual environ when i try and try django-admin.py, I get an error that I'm not being able to resolve. Could someone help me out please? Thanks a ton.

(virt1) C:\virt_env\virt1>Scripts\django-admin.py

I don't think easy_install knows about virtualenv. Use pip instead.
