I've already tried these troubleshooting steps: https://github.com/carlhuda/bundler/blob/1-2-stable/ISSUES.md我已经尝试过这些故障排除步骤: https : //github.com/carlhuda/bundler/blob/1-2-stable/ISSUES.md
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: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))
I know this answer includes a link, but this is not a link specific answer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 .您始终可以在rubygems.org上检查 gem 的反向依赖关系。 There's a link on the right side panel on the website.
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
So, in your case所以,在你的情况下
https://rubygems.org/gems/sys-proctable/reverse_dependencieshttps://rubygems.org/gems/sys-proctable/reverse_dependencies

Try the bundler-why plugin (inspired by yarn why
)试试bundler-why插件(灵感来自
yarn why
)
bundler plugin install bundler-why
bundle why tzinfo
# ransack -> activesupport -> tzinfo
# rspec-rails -> activesupport -> tzinfo
# business_time -> tzinfo
gem dependency --reverse-dependencies
will traverse a single edge of the paths . gem dependency --reverse-dependencies
将遍历路径的单个边缘。 In comparison, bundle why
will traverse all edges.相比之下,
bundle why
会遍历所有边。
