LoadError in rspec - ruby-on-rails

Question

I'm teaching myself ruby and have worked with Testfirst.org's curriculum, so I've used rspec before, but in a different directory. Now I'm I'm working through the following guide: http://guides.railsgirls.com/testing-rspec/
...at the first "rspec spec/lib/idea_spec.rb" I get:
Amys-MacBook-Air:railsgirls alightholder$ rspec spec/lib/idea_spec.rb
/Users/alightholder/.rvm/gems/ruby-1.9.3-p125/gems/rspec-core-3.1.2/lib/rspec/core/configuration.rb:1105:in `load': cannot load such file -- /Users/alightholder/Ruby/railsgirls_stuff/railsgirls/spec/lib/idea_spec.rb (LoadError)

from /Users/alightholder/.rvm/gems/ruby-1.9.3-p125/bin/rspec:19:in `<main>'
This looks like a configuration error to me. I've tried inserting /lib/ folder in between my idea_spec.rb and the /spec/ directory, but that didn't seem to help. I'm pretty sure I'm in the right folder and so far none of the guides on this site have been inaccurate or incomplete, so I'm at a loss why I'm getting a load error instead of a test run.
for "rspec spec/idea_spec.rb" I get:
/Users/alightholder/.rvm/rubies/ruby-1.9.3-p125/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- idea (LoadError)

Answer 1

Problem 1. idea_spec.rb (LoadError)
/Users/alightholder/.rvm/gems/ruby-1.9.3-p125/gems/rspec-core-3.1.2/lib/rspec/core/configuration.rb:1105:in `load': cannot load such file -- /Users/alightholder/Ruby/railsgirls_stuff/railsgirls/spec/lib/idea_spec.rb (LoadError)
Try executing rspec spec/idea_spec.rb, i.e., don't include lib.
It looks like you've initialized rspec in a directory called railsgirls which should produce a subdirectory called spec. Once you create your idea_spec.rb within the spec directory, the path to that file should simply be spec/idea_spec.rb as opposed to spec/lib/idea_spec.rb. I can't tell why the author of that guide has included lib. Also, be sure to execute rspec spec/idea_spec.rb from your railsgirls directory.
Problem 2. idea (LoadError)
/Users/alightholder/.rvm/rubies/ruby-1.9.3-p125/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- idea (LoadError)
Within idea_spec.rb, try changing
require "idea"
to
require "/Users/alightholder/Ruby/railsgirls_stuff/railsgirls/idea"
I'm assuming that your idea.rb is within your railsgirls directory -- if that's not right, replace the absolute path I used with the correct absolute path to your idea.rb.
After that, if you can run rspec without receiving a LoadError, then change from
require "/Users/alightholder/Ruby/railsgirls_stuff/railsgirls/idea"
(i.e., giving require an absolute path) to simply
require_relative "../idea"
