Some of the mentioned problems with the traditional method are partially solved with `pip install requests --user` but I understand that the bigger problem/main reason for virtualenv isn't helped by this. However, I was very surprised that the author didn't mention venv (http://docs.python.org/3.3/library/venv.html http://docs.python.org/3.3/library/venv.html) at all since it is basically virtualenv but part of the Python standard library.
