Hi, Running #rake spec seems to work as expected, however using cmd+r in textmate does not. I assume Textmate has some specific references to rails or ruby which I have not set. I have set the TM_RUBY to /usr/local/bin/ruby as suggested in the RSpec docs. I am running OS X 10.5 with a manually compiled ruby 1.8.6 (2007-03-13 patchlevel 0) [i686-darwin8.10.1] and gem 0.9.4. This was installed prior to upgrading to 10.5 which I hear includes its own version of ruby and gems. I am using rspec and rspec_on_rails rev 2962 (trunk) and have installed RSpec.tmbundle from the same revision. I am using using the trunk version as my project is using Rails RC1 (installed as the system version of Rails as opposed to frozen to the project, reported as version 1.99.0). When viewing a _spec.rb file and using cmd+r I get the following error: Cannot find gem for Rails ~>1.99.0: Install the missing gem with ''gem install -v=1.99 rails'', or change environment.rb to define RAILS_GEM_VERSION with your desired version. Thanks for any pointers, Andrew -- Posted via http://www.ruby-forum.com/.
