Install python and pip on Mac OS X

Mac OS X ships with python. You can see its version using

python --version

You can see where it is installed using

which python

You may want the latest version of python, or install python packages using pip. The way I found to get the latest versions of python on Mac OS X is using macports. To install macports download the packaged version from their site and install. Further instructions can be found on their install page.

Once macports is installed, you can install latest version of python 2 thus

sudo port install python27

To learn all python versions available

port list python*

To find out all python packages available

port list py*

To install pip

sudo port install py27-pip

Now that pip is installed you can install python packages. To see installed packages

pip-2.7 list

To search for available packages e.g. all packages with Django in the text

pip-2.7 search Django

To install django

sudo pip-2.7 install Django==1.4.8

To see more details about a package such as where it is installed

pip-2.7 show Django

To use pip packages with the version of python that ships with OS X, export their path to PYTHONPATH and call python

export PYTHONPATH=/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages
