I can't figure out why my RSPEC isn't working. I reinstalled RSPEC with sudo gem install rspec and then tried again to install with a specific version number (sudo gem install rspec -v 2.11.0) 
I continue to get the following error message and I cannot figure out what it means. I believe that I may or may not have version 1 also installed, not sure.
Castillo$ rspec document_spec.rb
