I added the pg gem to my gemfile
gem 'pg' When I run bundle install, I get this error:
Installing pg (0.10.1) with native extensions /Users/ben/.rvm/rubies/ruby-1.9.2-p0/lib/ruby/1.9.1/rubygems/installer.rb:483:in `rescue in block in build_extensions': ERROR: Failed to build gem native extension. (Gem::Installer::ExtensionBuildError) /Users/benhartney/.rvm/rubies/ruby-1.9.2-p0/bin/ruby extconf.rb checking for pg_config... no No pg_config... trying anyway. If building fails, please try again with --with-pg-config=/path/to/pg_config checking for libpq-fe.h... no Can't find the 'libpq-fe.h header *** extconf.rb failed *** 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. It seems I need to pass in this config parameter
--with-pg-config=/path/to/pg_config How can I do this when I use bundle install?

When you make a change to the Gemfile(5) and then run bundle install , Bundler will update only the gems that you modified. In other words, if a gem that you did not modify worked before you called bundle install , it will continue to use the exact same versions of all dependencies as it used before the update.
In the invoked popup, start typing bundler, select bundle install and press Enter . Select Tools | Bundler | Install from the main menu. Open the Gemfile, place the caret at any highlighted gem missing in the project SDK and press Alt+Enter . Select Install missing gems using 'bundler' and press Enter .
The most common question I've heard about Bundler is about the difference between bundle install and bundle update . In a nutshell: bundle install handles changes to the Gemfile and bundle update upgrades gems that are already managed by Bundler.
You need to set a build config option like so:
bundle config build.pg --with-pg-config=/path/to/pg_config More info can be found in the bundle config man page
