I meant how do you specify a version or other constraints with "require" for example: require 'gem_name' require can only take one parameter thus require 'gem_name', '>=1.23' responds with: ArgumentError: wrong number of arguments (2 for 1) and require 'gem_name >=1.23' responds with LoadError: no such file to load -- gem_name >=1.23 yes, I did use a gem name that I had on my machine I tried in irb: gem 'zentest', '>=3.4.3', response was Gem::LoadError: Could not find RubyGem zentest <>=3.4.3 gem 'zentest' response was Gem::LoadError: Could not find RubyGem zentest <>=0.0.0 I have gem 0.9.0 and ruby 1.8.5 on Windows
