Come faccio a sapere quale gemma ha una dipendenza specifica?

Question

Ho commentato una gemma, ma "bundle install" non verrà ancora eseguito. Come faccio a sapere quale gemma ha una dipendenza da sys-proctable?

$ bundle install

Could not find sys-proctable-0.9.2 in any of the sources 

$ grep proctable Gemfile 
    #gem 'sys-proctable', '0.9.2', :path => "vendor/gems" 

$ bundle list

Could not find gem 'rspec-rails (= 2.11.0) ruby' in the gems available on this machine. 

$ bundle viz

$ bundle -v 
Bundler version 1.3.0 

$ ruby -v 
ruby 1.9.3p385 (2013-02-06 revision 39114) [i386-cygwin]

Nella shell bash si può fare:

gem dependency name_of_the_gem --reverse-dependencies, per esempio:

gem dependency activesupport --reverse-dependencies        
Gem activesupport-2.3.14 
Used by 
actionpack-2.3.14 (activesupport (= 2.3.14)) 
activerecord-2.3.14 (activesupport (= 2.3.14)) 
activeresource-2.3.14 (activesupport (= 2.3.14)) 
...
