Run the pyvenvex script to create your virtual environments, in place of pyvenv, when you want Distribute and pip to be installed for you (this is how virtualenv sets up environments it creates). You can run the script with -h to see the command line options available, which are a superset of the pyvenv script.


I have a shell script for this:

#!/bin/sh
python3 -m venv $1
cd $1
.. bin/activate
wget http://python-distribute.org/distribute_setup.py
python distribute_setup.py
bin/easy_install pip
