How do I find out which gem has a specific dependency?

In the bash shell you can do:
在 bash shell 中，您可以执行以下操作：
gem dependency name_of_the_gem --reverse-dependencies, for instance:
gem dependency name_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))

我知道这个答案包含一个链接，但这不是特定于链接的答案
You can always check the reverse dependencies of a gem on rubygems.org. There's a link on the right side panel on the website.
您始终可以在rubygems.org上检查 gem 的反向依赖关系。网站右侧面板上有一个链接。
Or you can visit the site
或者您可以访问该网站
https://rubygems.org/gems/{gem_name}/reverse_dependencies
https://rubygems.org/gems/{gem_name}/reverse_dependencies
So, in your case
所以，在你的情况下
https://rubygems.org/gems/sys-proctable/reverse_dependencies
https://rubygems.org/gems/sys-proctable/reverse_dependencies
