You need to have the PostgreSQL libraries and build the basics to compile your own PG extension.

For PostgreSQL libraries

sudo apt-get install libpq-dev


To create essentials

sudo apt-get install build-essential

Assuming you are on an ubuntu machine

I see you have been working with RoR for a while now, so you have a development environment customized to your liking, but I highly recommend ThoughtBot (the creator of FactoryGirl and PaperClip) for a very simple (it couldn't be easier) development.

This is a script for OS X that configures Postgres, Foreman, Heroku Toolbelt, ImageMagick, Rbenv, Redis, Tmux, and more. Don't worry, as it will automatically skip over what you've already installed.

To install Thoughtbot setup, run the script below:



curl --remote-name https://raw.githubusercontent.com/thoughtbot/laptop/master/mac
less mac
sh mac 2>&1 | tee ~/laptop.log
