Can't Install Pg Gem on Rails

Can't install pg gem on Rails

You need to configure pg correctly.

Run:

bundle config build.pg --with-pg-config=/Applications/Postgres.app/Contents/Versions/(YOUR POSTGRES VERSION)/bin/pg_config

Then try to run bundle:

bundle install

I guess you don't have postgres installed in your system. You could either install postgresql via homebrew/macports or disable the installation of production gems with:

bundle install --without production

The message you're getting is a clear indication that you lack something for the correct installation of that gem:

Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers. Check the mkmf.log file for more
details. You may need configuration options.

There is no Windows native version of latest release of pg (0.10.0) released yesterday, but if you install 0.9.0 it should install binaries without issues.

Installation of the gem will only require you provide additional options to gem installation (like --with-pg-dir)

subst X: "C:\Program Files (x86)\PostgreSQL\8.3"
gem install pg -- --with-pg-dir=X:
subst X: /D

On a Mac:
