I'm working on a Ruby gem. The "rake" command works as expected in my Mac setup, but when I enter the "rake command" on my Linux setup in VirtualBox with a FRESH Ruby on Rails setup, I get the following error message: rake aborted! cannot load such file -- rspec/core/rake_task /home/jhsu/lottosim/Rakefile:2:in `<top (required)>' (See full trace by running task with --trace) I tried using the .ruby-version file to specify Ruby 2.0.0, but that doesn't solve the problem. I know that most people don't keep a fresh installation of Ruby on Rails in VirtualBox, but I know that there is a critical detail that I'm missing in the gemspec or elsewhere in my project. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
