I'm desperately trying to successfully install psycopg2 but keep running into errors. The latest one seems to involve it not being to find "stdarg.h" (see code below). However I can see with my own eyes that a file called stdarg.h exists at /Developer/SDKs/MacOSX10.4u.sdk/usr/include/stdarg.h (where it claims it can't find anything) so I've no idea what to do about it.

I'm running Mac OS 10.6.3 and within the last few days I've made sure I have all the latest OS developer tools.

I have Python 2.6.2 and PostgreSQL 8.4 if that makes any difference.

I don't know your specific problem but i recommend you to install it using macports.
Installing psycopg2 is as simply as: 

sudo port install py26-psycopg2

    @cojadate it depends on what version of Python you are currently using. If you are running with python2.6 , py26-psycopg2 is the right choice. psycopg2 is surely installed but i guess is not in your Python path. – systempuntoout Jun 15 '10 at 14:10

    @cojadate If you installed psycopg2 using MacPorts, you need to make sure that you're using the ports version of Python instead of the one that ships with OSX. Make sure `/opt/local/Library/Frameworks/Python.framework/Versions/Current/bin/` or similar is in your `PATH` before `/usr/bin` or what-have-you. – Hank Gay Jun 18 '10 at 17:17

The following works for me:

  1. $ mkvirtualenv --no-site-packages --distribute psycopg2_test
  2. $ cd $VIRTUAL_ENV
  3. $ pip install psycopg2

Notes

  • I installed my base Python via MacPorts.

  • The above commands make use of:

  • I bootstrapped pip via the following:

    1. wget http://python-distribute.org/distribute_setup.py
    2. python distribute_setup.py
    3. easy_install pip

UPDATE: I realize it seems like a lot of yak shaving, but learning how to use virtualenv and friends is an up-front investment that pays off pretty quickly, especially when dealing with projects that have a lot of dependencies.

I actually had a very similar problem as this (except with OSX Lion, Python 2.7) Can't install psycopg2 in virtualenv "error: stdarg.h: No such file or directory".

I ended up using this solution: https://stackoverflow.com/a/8834568/396327

Basically, uninstalling/reinstalling XCode from scratch (and a few more hacks to get it to recognize gcc-4.2).
