This guide assumes a fresh install of Mac OSX 10.7 Lion.
Follow https://github.com/mxcl/homebrew/wiki/installation to get the basic setup up and running. (the default, not the alternate installs).
Don't forget to install the requirements (Xcode, X11, Java Developer Update) mentioned in the installation guide.
Please note the recommendations below.
Installing as root is not recommended by the homebrew authors. But I hate nothing more than accidentally installing a
python package globally when I forget activating a virtualenv. To prevent this I decided to create a dedicated user
called brew who has control over /usr/local/. So for everything brew related and to install global
python/ruby/whatever packages it is necessary to su to brew: sudo su - brew.
See https://github.com/mxcl/homebrew/wiki/Homebrew-and-Python and https://github.com/mxcl/homebrew/wiki/Gems%2C-Eggs-and-Perl-Modules for details.
the basics:
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, easy_install or 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.
If you decided to make a dedicated brew user, do this for this user as well.
~/.bash_profile or ~/.profile (I recommend .profile because it works in bash and zsh:
PATH=/usr/local/bin:/usr/local/share/python:$PATH export PATH
Note
remember to open a new terminal or call source ~/.bash_profile in all of your open terminal windows to get
PATH updated.
Before installing stuff with pip, make sure the above PATH changes worked and you are using the correct version.:
pip --version
should return something like (a path with /usr/local/):
pip 1.1 from /usr/local/lib/python2.7/site-packages/pip-1.1-py2.7.egg (python 2.7)
install some dependencies:
brew install libjpeg brew install lcms brew install libtiff
If you don't need FREETYPE support, the regular pip install PIL will work. There is no real need to install PIL
globally then.
If you need FREETYPE, choose one of these three options. I recommend PIL with patching setup.py:
Since PIL is not packaged correctly, setup.py needs to be tweaked.
Use the newest source version of PIL from http://www.pythonware.com/products/pil/ , download, upack and edit
FREETYPE_ROOT = ("/usr/x11/lib","/usr/x11/include",) in setup.py. Then:
python setup.py build_ext -i python setup.py install
This method has the advantage, that other packages that have PIL as a dependency will detect that it is already installed.
Pillow is an alternative Distribution of PIL:
pip install Pillow
Pillow does a great job of finding all the dependencies it needs in OSX. But it sucks a bit if an other packages list PIL as a dependency, because Pillow will not be recognized as a valid PIL installation and PIL will be installed again.
Homebrew has a formula for PIL:
brew install pil
Attention!
This may produce the dreaded AccessInit: hash collision: 3 for both 1 and 1 error if some apps import PIL
as from PIL import Image and others as import Image.
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
aggdraw provides much better anti-aliasing than PIL . And lots of other stuff.
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://[email protected]/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 ghostscript brew install imagemagick # barcode (qrcode and others) reading lib brew install zbar pip install zbar
server:
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/5.5.14/com.mysql.mysqld.plist ~/Library/LaunchAgents/ launchctl load -w ~/Library/LaunchAgents/com.mysql.mysqld.plist # set a root password /usr/local/Cellar/mysql/5.5.20/bin/mysqladmin -u root password 'new_password'
client:
brew install mysql-connector-c
On my machine brew did not link mysql_client in /usr/local/bin, so I had to do it manually. This is probably a bug homebrew and is likely to be fixed soon.:
cd /usr/local/bin ln -x ../Cellar/mysql/<mysql-version>/bin/mysql_config ./ pip install mysql-python
server:
PYTHON=/usr/local/bin/python brew install postgresql # look at the instructions brew prints after installation. this is the short version: initdb /usr/local/var/postgres mkdir -p ~/Library/LaunchAgents cp /usr/local/Cellar/postgresql/9.1.3/homebrew.mxcl.postgresql.plist ~/Library/LaunchAgents/ launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist createuser # create the initial postgres user
python client bindings (does not work without the server):
pip install psycopg2
packages:
brew install postgis # this will handle installing postgres, geos, proj4, and postgis pip install numpy 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 template_postgis:
createdb -T template_postgis [yourdatabase]
Alternatively it is possible to enable spatial functions on a existing databases by calling the above commands for
creating template_postgis (except createdb, of course). Just use your existing database name instead of
template_postgis.
brew install solr
brew install mongodb # look at the instructions brew prints after installation. this is the short version: cp /usr/local/Cellar/mongodb/1.8.2-x86_64/org.mongodb.mongod.plist ~/Library/LaunchAgents/ launchctl load -w ~/Library/LaunchAgents/org.mongodb.mongod.plist
Mongohub (http://mongohub.todayclose.com/) is an awesome OSX ui for mongodb.
general:
brew install wget
hub is a useful extension to make git github aware. gist is a commandline interface to github gists.
git:
brew install git brew install hub brew install git-flow brew install gist brew install git-extras git-hg git-multipush git-sh git-svn-abandon git-utils
mercurial (hg):
pip install mercurial
Attention!
Installation of the mercurial 2.1.1 package from pypi does not work.
See http://mercurial.selenic.com/bts/issue3277 for details. Until 2.1.2 is released I recommend downloading
the source and running python setup.py install.
Attention!
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
brew install ssh-copy-id brew install vcprompt pip install virtualenv pip install virtualenvwrapper brew install bash-completion pip install ipython pip install bpython
and virtuelenvwrapper. See http://www.doughellmann.com/docs/virtualenvwrapper/ for details.
pip install virtualenv pip install virtualenvwrapper
Add this to you shell (.bash_profile or similar):
export VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python source /usr/local/share/python/virtualenvwrapper.sh
the most useful package. this one is a must.:
brew install cowsay cowsay You can now code python on OSX. Congratulations!
