Answer 1

You should add python requirements used in Postgres on Ubuntu. Run:

sudo apt-get install libpq-dev python-dev

Answer 2

Have you installed python-dev? If you already have, try also installing libpq-dev

sudo apt-get install libpq-dev python-dev

From the article: How to install psycopg2 under virtualenv

Answer 3

I recommend that you try to use Postgres.app. (http://postgresapp.com) This way you can easily turn Postgres on and off on your Mac. Once you do, add the path to Postgres to your .profile file by appending the following:

PATH="/Applications/Postgres.app/Contents/Versions/latest/bin:$PATH"

Only after you added Postgres to your path you can try to install psycopg2 either within a virtual environment (using pip) or into your global site-packages.

Answer 4

pg_config is in postgresql-devel (libpq-dev in Debian/Ubuntu, libpq-devel on Centos/Cygwin/Babun.)

Answer 5

For mac users, extend your path variable to include PostgreSQL like this export PATH=$PATH:/Library/PostgreSQL/12/bin.

Answer 6

For those running OS X, this solution worked for me:

1) Install Postgres.app:

http://www.postgresql.org/download/macosx/

2) Then open the Terminal and run this command, replacing where it says {{version}} with the Postgres version number:

export PATH=$PATH:/Applications/Postgres.app/Contents/Versions/{{version}}/bin

e.g.

export PATH=$PATH:/Applications/Postgres.app/Contents/Versions/9.4/bin
