ImportError for Python3

Virtualenv fails to create a python 3 environment, but works on 2.7:

$  python3 --version
Python 3.4.1
$ virtualenv --version
1.11.6
$ virtualenv --python=/usr/local/bin/python3 python3project

I had to revert the fix to this, because 12.0 was severely broken and nothing I could do seemed to fix it. Details - https://etherpad.openstack.org/p/pydistutils-issues.

A workaround for this problem I found was to uninstall the pies2overrides package in my system python.

+1 getting this as well. As a workaround I solved it by typing:

python3.4 `which virtualenv` --python=`which python3.4` --no-site-packages myvirtualenv

the key was to call the virtualenv script directly from python3.4.

ImportError: cannot import name 'IntEnum'

My computer is windows installed python 2.7 and python 3.5.

It seems IntEnum not exists in python 2.7
