I'm getting errors when running

$ brew install postgresql

==> Downloading http://ftp.postgresql.org/pub/source/v9.1.2/postgresql-9.1.2.tar.bz2
File already downloaded in /Users/neil/Library/Caches/Homebrew
Warning: Detected a framework Python that does not have 64-bit support in:
/Library/Frameworks/Python.framework/Versions/Current/Python

e configure script seems to prefer this version of Python over any others,
 you may experience linker problems as described in:
http://osdir.com/ml/pgsql-general/2009-09/msg00160.html

 fix this issue, you may need to either delete the version of Python
own above, or move it out of the way before brewing PostgreSQL.

te that a framework Python in /Library/Frameworks/Python.framework is
e "MacPython" version, and not the system-provided version which is in:
/System/Library/Frameworks/Python.framework
==> ./configure --disable-debug --prefix=/usr/local/Cellar/postgresql/9.1.2 --datadir=/usr/local/Cellar/postgresql/9.1.2/shar
^C

Here's where python is located.

$ which python

/usr/local/bin/python

I modified my ~/.zshrc PATH from

export PATH=/Library/Frameworks/Python.framework/Versions/2.7/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/X11/bin

to

export PATH=/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/X11/bin

And although I'm getting python 64-bit errors, my version of python is 64-bit according to this SO post:

$ python -c 'import struct;print( 8 * struct.calcsize("P"))'

64

The problem pointed out in the referenced mailing list post is that the configure step isn't impacted by the PATH here. There's a whole other mechanism used to find things to link against; see Where do I set DYLD_LIBRARY_PATH on Mac OS X for a quick intro. You could try the suggested workaround given by the brew script--rename /Library/Frameworks/Python.framework/Versions/Current/Python to something else to get it out of the linker's search path, repeat the brew install, then put it back.

If you don't need Python bindings in your PostgreSQL, you can also just install it without Python bindings using brew install postgresql --no-python.

This command is installing the server, not the python bindings. Is that what you want? There is a installer for osx that will install the server for you.

Once you have done that, you can install the psycopg2 bindings directly from source.

  • [Heroku](http://devcenter.heroku.com/articles/local-postgresql#macintosh) recommends using homebrew to use PostgreSQL for local Rails development. I do not understand why python bindings are being installed. – paniwani Feb 28 '12 at 19:11
  • Homebrew includes python, ruby, and other language bindings by default when installing a program or server, instead of providing them as separate packages. So the 'postgresql' package includes the server, the client, and language bindings. – Andrew Janke May 01 '13 at 01:16
