Postgres uses its own install of Python. That's why it does not find the system-installed ones. The 'edb' folder is created when using the EnterpriseDB installer for Postgres. There may be a way to tell Postgres to use the System install, but I do not know how. – Crashmeister Jun 26 '18 at 18:29.

Psycopg2 requires the PostgreSQL libpq libraries and the pg_config utility, which means you need a decent chunk of PostgreSQL to be installed. You could install Postgres and psycopg2 via MacPorts, but the version situation is somewhat messy--you may need to install a newer Python as well, particularly if you want to use a recent version of the PostgreSQL libraries. Depending on what you want to do, for example if you have some other Python you want to use, it may be easier to grab a more standard PostgreSQL install and just build psycopg2 yourself. That's pretty easy if you've already got gcc etc. Installed, typically the only build issue is making sure it looks in the right place for the libpq include files.

See and for a few recipes covering the usual build issues you might run into. You can install from an. Allow it to change your memory settings and reboot (it's reversible by removing '/etc/sysctl.conf') - the README file (which tells you to do this yourself) is out of date. Then use (or get, if you haven't already and). Check where the PostgreSQL installer has put things - mine is here: /Library/PostgreSQL/8.4/ Add this path to your.bash_login or.bash_profile file in your home directory (make one if you don't have it already): export PATH='/Library/PostgreSQL/8.4/bin:$PATH' Then (on an Intel iMac running OS 10.4.11 and Python 2.6) do: sudo easy_install psycopg2 This found psycopg2 2.0.11 and (on my setup) gave the following readout: warning: no files found matching '*.html' under directory 'doc' warning: no files found matching 'MANIFEST' zip_safe flag not set; analyzing archive contents. Adding psycopg2 2.0.11 to easy-install.pth file Installed /Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/psycopg2-2.0.11-py2.6-macosx-10.3-i386.egg Processing dependencies for psycopg2 Finished processing dependencies for psycopg2 So I guess I have no psycopg2 documentation. Which is best a pc or mac for processing photos. However, despite the warnings, I could then do: python >>>import psycopg2 >>> Success?

I haven't tried running anything yet, but getting a successful import was the first goal. BTW this was for Django.

I'm not sure if the current Django release is compatible with PostGIS 2.0. You might like to try installing PostGIS 1.5.

This may also mean installing PostgreSQL 9.0.
