'Could not find pg-0.12.2 in any of the sources' when running rspec
I'm working on building the twitter clone app in Hartl's Rails Tutorial. I cloned my git repo (https://github.com/stewartmccoy/rails_tutorial) and put code on to my personal computer, which had previously been on my work computer. So, my developer environment might be slightly different than what's specified in my Gemfile.
My environment: Mac OS 10.6.8 Rails 3.2.13 ruby 1.9.3p392 (2013-02-22 revision 39386) [x86_64-darwin10.8.0]

Anyway, I'm trying to run the test just after Listing 8.18 (http://ruby.railstutorial.org/chapters/sign-in-sign-out#sec-reviewing_form_submission):
$ bundle exec rspec spec/models/user_spec.rb
And I get this error:
Could not find pg-0.12.2 in any of the sources
Run `bundle install` to install missing gems.
So, I run bundle install and and get this error:

Make sure that `gem install pg -v '0.12.2'` succeeds before bundling.

Suggestions?
Thanks so much in advance for your help!
Answer
You should check what adapters you have on config/database.yml. Probably you have setup the postgres or pg adapter with the test environment.
However, on your Gemfile, you have setup postgres just for production:
group :production do
gem 'pg', '0.12.2'
end
if you add the test environment and run bundle again, it should work:
group :test, :production do
gem 'pg', '0.12.2'
end
Also see the solution from this answer:
Try to install the gem with this command:
gem install pg -- --with-pg-config= 'PATH_TO_YOUR_PG_CONFIG'
If you don't know where your pg_config is, run this command:
which pg_config
BTW, did you already install postgres on your desktop? All you need is the postgres development package to install the gem.
