Install Python

1. You will propably need the GIS features of Eden. Before you proceed install the GDAL framework
   • ​http://trac.osgeo.org/gdal/wiki/DownloadingGdalBinaries

2. You also need to install some modules of python

   STATIC_DEPS=true sudo easy_install lxml
   sudo easy_install shapely
   sudo easy_install reportlab
   sudo easy_install xlwt
   sudo easy_install pyserial
   sudo easy_install tweepy
   

3.In case you want to use PostgreSQL - PostGIS (I assume you already installed the spatial modules before)

Install the one clickInstaller sponsored by EnterpriseDB PostgreSQL and select also installation of postgis. Then based on this article ​http://schwuk.com/articles/2009/09/10/psycopg2-on-os-x install the python database driver

sudo easy_install pip
PATH=$PATH:/Library/PostgreSQL/8.4/bin/ sudo pip install psycopg2
defaults write com.apple.versioner.python Prefer-32-Bit -bool yes

without the last you will not be able to see available the PostgreSQL driver when web2py launch

Trouble?

• lxml can give trouble on OS X. Try:
  • STATIC_DEPS=true sudo easy_install lxml (adapted from ​this blog post)
  • remove other libxml2 versions, such as may have been installed by fink or MacPorts - ONLY works in unmodified python setup. In case you have modified your python you must link some how the python directory with /frameworks/python otherwise lxml will not being found(not tested)
• Mac OS X: Xcode to compile some Python libraries: ​http://developer.apple.com/technologies/tools/xcode.html
