我如何找出哪个gem具有特定的依赖关系？ [英] How do I find out which gem has a specific dependency?

问题描述

我评论了一个gem，但'捆绑安装'仍然不会运行。我如何找出哪个gem依赖于sys-proctable？

  $ bundle install 
从https：//rubygems.org / .......获取gem元数据..

无法在任何源代码中找到sys-proctable-0.9.2 
 
 $ grep proctable Gemfile 
 #gem'sys-proctable'，'0.9.2'，：path => 供应商/宝石
 
 $捆绑列表

我已经尝试了这些故障排除步骤： https://github.com/carlhuda/bundler/blob/1-2-stable/ISSUES.md

解决方案

在bash shell中，您可以执行以下操作：

例如：

  gem dependency activesupport --reverse-dependencies 依赖项
 Gem activesupport-2.3.14 
由
使用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 commented out a gem, but 'bundle install' still won't run. How do I find out which gem has a dependency on sys-proctable?

$ bundle install
Fetching gem metadata from https://rubygems.org/.........
Fetching gem metadata from https://rubygems.org/..
Resolving dependencies...
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
Resolving dependencies...
Could not find gem 'rspec-rails (= 2.11.0) ruby' in the gems available on this machine.

$ bundle viz

$ bundle -v

$ ruby -v

I've already tried these troubleshooting steps: https://github.com/carlhuda/bundler/blob/1-2-stable/ISSUES.md

解决方案

In the bash shell you can do:

gem dependency name_of_the_gem --reverse-dependencies, for instance:

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))
...
