Question

Bundler似乎正在安装我不需要的宝石，而且它们正在引发问题。我们举两个例子：timers和celluloid

bundle install正在安装timers所需的celluloid，但我不知道为什么会安装赛璐珞。我正在使用ruby 1.8.7和rails 3.2.13。

为什么要安装celluloid？如何查找未安装（无法安装）的gem的反向依赖项？

我的Gemfile

source "https://rubygems.org"

gem "rails", "3.2.13"
gem "mysql2", "~> 0.3.13"
gem "json", "~> 1.8.0"

group :assets do
  gem "guard-rails-assets", "~> 0.1.3"
  gem "sass-rails", "~> 3.2.6"
  gem "coffee-rails", "~> 3.2.2"
  gem "uglifier", "~> 1.0.3"
end

gem "jquery-rails", "~> 3.0.4"
gem "simple_form", "~> 2.1.0"
gem "bootstrap-sass", :path => "gems/bootstrap-sass-c0e12a90ba3e"
gem "client_side_validations", "~> 3.2.6"
gem "client_side_validations-simple_form", "~> 2.1.0"
gem "therubyracer", :platform => :ruby
gem "require_relative", "~> 1.0.3"
gem "icalendar", "~> 1.4.3"
gem "whenever", "~> 0.8.4", :require => false
gem "jquery-cookie-rails", "~> 1.3.1"
gem "hominid", "~> 3.0.5"

bundle install

Gem::InstallError: celluloid requires Ruby version >= 1.9.2.
An error occurred while installing celluloid (0.15.2), and Bundler cannot continue.
Make sure that `gem install celluloid -v '0.15.2'` succeeds before bundling.

Answer 1

您可以让Bundler向您显示完整的依赖关系图：

sudo apt-get install graphviz
# Or however you install graphviz on your platform; http://www.graphviz.org/
gem install ruby-graphviz
bundle viz

当前目录中的.png将包含完整的依赖关系图。

或者，您可以通过查看Gemfile.lock文件来追溯依赖关系。在GEM部分中，每个宝石出现时都会在其下方缩进，因此您可以追溯到您要求的宝石：

GEM
# ...
    listen (2.4.0)
      celluloid (>= 0.15.2)
      rb-fsevent (>= 0.9.3)
      rb-inotify (>= 0.9)
# ...
    guard (2.2.5)
      formatador (>= 0.2.4)
      listen (~> 2.1)
      lumberjack (~> 1.0)
      pry (>= 0.9.12)
      thor (>= 0.18.1)
# ...

根据您的Gemfile判断，我猜测Celluloid被包含为guard-rails-assets的传递依赖。

Answer 2

您可以使用gem dependency -R celluloid查找反向依赖项。在我的系统上，这会产生：

Gem celluloid-0.15.2
  benchmark_suite (>= 0, development)
  guard-rspec (>= 0, development)
  rake (>= 0, development)
  rspec (>= 0, development)
  timers (~> 1.1.0)
  Used by
    listen-2.1.1 (celluloid (>= 0.15.2))
