# First, install Postgres.app from http://postgresapp.com/
# Next, install pip using the OS X system easy_install
sudo easy_install pip
# Now you can use pip to install psycopg2 - afteradding the Postgres.app bin directory to your path
PATH=$PATH:/Applications/Postgres.app/Contents/Versions/9.5/bin/ sudo pip install psycopg2
# The above PATH trick works using virtualenv as well
