问题 At runtime, after bundler setup is complete, and groups are applied, what is the best way to programmatically check if a given gem_name is in the bundle? By reading the source, I've discovered Bundler.definition, e.g. gem_name = 'banana' Bundler.definition.dependencies.map(&:name).include?(gem_name) but unable to find documentation 1 , I don't know if this is the recommended usage. Update: It looks like Bundler::Definition#dependencies returns all dependencies, irrespective of groups. As an

问题 From a running rails app is there a way to enumerate the list of dependencies for the application? Assume I don't have access to the Gemfile or Gemfile.lock files.

A developer by the name of Matt Hutchinson wrote a Gem for easily connecting to the API. He has a set of instructions next to his source files on github. Anyway, It looks pretty simple but in trying to implement it I get this error every time: undefined method `acts_as_textcaptcha' for #<Class:0x104098508> Rails.root: /Users

问题 I have been having problems after updating from p247 to the latest patch for Ruby 2.0.0 (P353) using the latest version of RVM.

问题 I was trying to create a fresh installation of Ruby and Rubygems using RVM on Ubuntu 13.10. I had already had an installation before which somehow got corrupted.
