Steps I have taken

  • I tried addding "gem 'postgres-pr', :require => 'pg'" to the gemfile
  • Have tried installing multiple variations of the postgres gem,
    • postgres-pr
    • pg
    • ruby-pg

I continually get this error when trying to run rake db:migrate

rake aborted!
no such file to load -- pg

You may need to upgrade your version of Rails to 3.0.1 - 3.0.9 and also run gem install pg. Then just for good measure re-run bundle install.

You need to specify the correct platform for the gem. In my Gemfile, I have:

group :development, :test do
  gem 'pg', :platforms => :mingw
end

(The group is there because I deploy to a Unix box, where the platform is obviously different). I seem to remember that I also needed the DevKit for this to work.

I got the pg gem installed with plaform mingw and then I put devkit into my home folder for cygwin and i'm still getting the rake aborted! no such file to load -- pg error – Brian Mar 24 '11 at 16:47
Ah, you don't need the DevKit after gem installation, it is necessary for some gems to build. – jhwist Mar 24 '11 at 18:55

You need to install pg and add to your Gemfile

gem 'pg'
