推荐答案

在 bash shell 中你可以这样做:

In the bash shell you can do:

gem 依赖名_of_the_gem --reverse-dependencies

例如:

$ 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))
