Why I love virtualenv and pip.
We use virtualenv and pip extensively here, with virtualenvwrapper.
mkvirtualenv <project>
workon <project>
pip install -r requirements.txt
It just works. I don't spend any time on it. Our developers don't have any problems with it. All the other considerations in the article we either handle as you're meant to, or understand the limitations.Still, looking forward to some interesting comments on here.
