OSX Developer System installation
This guide assumes a fresh install of Mac OSX 10.6 Snow Leopard.
See https://github.com/mxcl/homebrew/wiki/Installation for details.
- Make sure X11 is installed (it's included in the default installation on Snow Leopard)
- Install xcode4 - if you are downloading it from AppStore with Lion, remember to run the file "install Xcode", that will be in the Application folder, after the installation has completed
- run this simple script:
ruby -e "$(curl -fsSL https://raw.github.com/gist/323731/39fc1416e34b9f6db201b4a026181f4ceb7cfa74)"
- edit PATH (e.g in
export PATH=/usr/local/bin:$PATH(remember to logout and login again for the changes in .bash_profile to get picked up)
python and stuff
See https://github.com/mxcl/homebrew/wiki/Homebrew-and-Python for details.
brew install python /usr/local/share/python/easy_install pip /usr/local/share/python/pip install --upgrade distribute
homebrew sets things up so that all packages installed via
python setup.py install,
pip get their commands installed to
/usr/local/share/python/ by default (see the above link for an explanation). So the first rule of business is to add that path to your
PATH. Also if you want to use your homebrew python (and other homebrew stuff) by default,
/usr/local/bin should be all the way at the front of your
PATH=/usr/local/bin:/usr/local/share/python:$PATH export PATH
remember to open a new terminal or call
source ~/.bash_profile in all of your open terminal windows to get
Before installing stuff with pip make sure you are using the correct version.:
should return something like:
pip 1.0 from /usr/local/lib/python2.7/site-packages/pip-1.0-py2.7.egg (python 2.7)
PIL with pillow (recommended)
install some dependencies:
brew install jpeg lcms pip install Pillow
PIL with patching setup.py
Since PIL is not packaged correctly, setup.py needs to be tweaked.
Use this version of pil (http://dist.repoze.org/PIL-1.1.6.tar.gz) and install it with
FREETYPE_ROOT = ("/usr/x11/lib","/usr/x11/include",) in setup.py. Then:
python setup.py build_ext -i python setup.py install
Some python packages don't work when PIL is installed with the
PIL prefix. Add a
PIL.pth file in
/usr/local/lib/python2.7/site-packages/PIL.pth containing the string
PIL. Now both
from PIL import Image and
import Image will work.
This oneliner will do exactly that:
echo "PIL" > /usr/local/lib/python2.7/site-packages/PIL.pth
use this version: http://bitbucket.org/2degrees/aggdraw-64bits/src
this needs mercurial to be installed (
pip install mercurial)
mkdir ~/tmp cd ~/tmp hg clone https://firstname.lastname@example.org/2degrees/aggdraw-64bits cd aggdraw-64bits /usr/local/bin/python setup.py build_ext -i /usr/local/bin/python setup.py install
Enabling freetype does not work for me. Please share if you find a way :-)
brew install mysql # look at the instructions brew prints after installation. this is the short version: unset TMPDIR mysql_install_db --verbose --user=`whoami` --basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql --tmpdir=/tmp mkdir -p ~/Library/LaunchAgents cp /usr/local/Cellar/mysql/5.5.12/com.mysql.mysqld.plist ~/Library/LaunchAgents/ launchctl load -w ~/Library/LaunchAgents/com.mysql.mysqld.plist # set a root password /usr/local/Cellar/mysql/5.5.12/bin/mysqladmin -u root password 'new-password'

python client bindings (does not work without the server):
pip install psycopg2
postgis / geodjango
brew install postgis # this will handle installing postgres, geos, proj4, and postgis brew install gdal
creating a spatially-enabled database template:
createdb template_postgis # create a standard postgres db createlang plpgsql template_postgis # enable the PL/pgSQL PostGIS functions psql -d template_postgis -f /usr/local/Cellar/postgis/1.5.3/share/postgis/postgis.sql psql -d template_postgis -f /usr/local/Cellar/postgis/1.5.3/share/postgis/spatial_ref_sys.sql
Creating a new database based on
createdb -T template_postgis [yourdatabase]
Alternatively it is possible to enable spatial functions on a existing databases by calling the above commands for creating
createdb, of course). Just use your existing database name instead of
Other useful tools
git and hg:
brew install wget brew install git hub pip install mercurial
I had problems installing mercurial with pip on a 32bit MacBook Pro (Core Duo and less) because it failed to compile the 64bit version of the mercurial.base85 extension. So I downloaded the mercurial 1.8.2 package from pypi and removed
-arch x86_64 near the end of
setup.py and the ran
python setup.py install and it worked fine.
install and make the command globally available:
brew install gettext brew link gettext
more useful stuff
brew install ssh-copy-id brew install vcprompt pip install virtualenv pip install virtualenvwrapper brew install bash-completion pip install ipython
the most useful package. this one is a must.:
brew install cowsay cowsay You can now code python on OSX. Congratulations!
