virtualenvwrapper and Python 3

Question

I installed python 3.3.1 on ubuntu lucid and successfully created a virtualenv as below

virtualenv envpy331 --python=/usr/local/bin/python3.3

Answer 1

If you already have python3 installed as well virtualenvwrapper the only thing you would need to do to use python3 with the virtual environment is creating an environment using:

which python3 #Output: /usr/bin/python3
mkvirtualenv --python=/usr/bin/python3 nameOfEnvironment

Or, (at least on OSX using brew):

mkvirtualenv --python=`which python3` nameOfEnvironment

Start using the environment and you'll see that as soon as you type python you'll start using python3
