Problem with virtualenv in Mac OS X

Question

I\'ve installed virtualenv via pip and get this error after creating a new environment:

selenium:~ auser$ virtualenv new  
New pyt         


        

Answer 1

I had this same issue, and I can confirm that the problem was with an outdated virtualenv.py file.

It was not necessary to do a whole install --upgrade.

Replacing the virtualenv.py file with the most recent version sufficed.
