It can be also useful, but not mandatory, to use a complete IDE with Python autocompletion, debugging facilities and so on. Now that we have Python 3 installed, we can use any good text editor to write some code. No error, everything is OK! Note that, with Homebrew, Python 3 packages are installed under /usr/local/lib/python3.3/site-packages. Then launch the python3 interactive console and test that SQLAlchemy is installed now $ python3 If we want to install SQLAlchemy for instance, type pip3 install sqlalchemy Once via pip for Python 2.7 and once via pip3 for python 3.3.

There are many package installers on OSX but I find Homebrew very pleasant, simple and convenient.
