Gemspec 依赖项未使用 Gemfile 加载

Question

例如，给定 Gemspec 文件：

$:.push File.expand_path("../lib", __FILE__)

# Maintain your gem's version:
require "github_stats/version"

# Describe your gem and declare its dependencies:
Gem::Specification.new do |s|
  s.name        = "github_stats"
  s.version     = GithubStats::VERSION
  s.authors     = ["Pura Dawid"]
  s.email       = ["puradawid@gmail.com"]
  s.homepage    = "https://github.com/puradawid/github_stats"
  s.summary     = "Project repository model wrapper and statistic fetcher."
  s.description = ""
  s.license     = "MIT"

  s.files = Dir["{app,config,db,lib}/**/*", "MIT-LICENSE", "Rakefile", "README.rdoc"]
  s.test_files = Dir["test/**/*"]

  s.add_dependency "rails", "~> 4.1.8"
  s.add_runtime_dependency "github_api", "0.12.3"

  s.add_development_dependency "sqlite3"
end

还有 Gemfile 看在上帝的份上：

source 'https://rubygems.org'

# Declare your gem's dependencies in github_stats.gemspec.
# Bundler will treat runtime dependencies like base dependencies, and
# development dependencies will be added by default to the :development group.
gemspec

# Declare any dependencies that are still in development here instead of in
# your gemspec. These might include edge Rails or gems from your path or
# Git. Remember to move these dependencies to your gemspec before releasing
# your gem to rubygems.org.

# To use a debugger
#gem 'byebug', group: [:development, :test]

#gem 'github_api', '0.12.3'

group :development do
  gem 'byebug'
  gem 'mocha'
  gem 'guard'
  gem 'guard-minitest'
end

group :test do
  gem 'rake'
end

github_api 被注释掉了（如果我把它放在这里，它显然有效）。

如您所见，github_api 被添加为依赖项（它是 gem）。它在工作吗？当然不是。输入 Bundler.require 给我：

[<Bundler::Dependency type=:runtime name="github_stats" requirements=">= 0">,
<Bundler::Dependency type=:development name="sqlite3" requirements=">= 0">,
<Bundler::Dependency type=:runtime name="byebug" requirements=">= 0">,
<Bundler::Dependency type=:runtime name="mocha" requirements=">= 0">,
<Bundler::Dependency type=:runtime name="guard" requirements=">= 0">,
<Bundler::Dependency type=:runtime name="guard-minitest" requirements=">= 0">,
<Bundler::Dependency type=:runtime name="rake" requirements=">= 0">]

我看到了这个问题 here，但我没有看到一个干净的解决方案。

我怎么了？ add_dependency 效果不佳 add_development_dependency 但最后一个在这里完全没有意义，即使我也试过了。

 Bundler version 1.8.4
 => ruby-2.1.5 [ x86_64 ]

感谢大家的帮助！

如果您有兴趣 - issue 1041。看完之后我明白了，这是标准行为。争论的焦点是依赖捆绑器来要求您的 gem 依赖项是一种不好的做法。你应该明确要求你的 gems 因为你的 gem 应该在没有捆绑器的情况下工作。 Bundler 被广泛使用但不是像 ruby gems.

这样的标准

如果您仍然需要访问捆绑程序所需的 gems，您可以使用此 hack：

Bundler.definition.specs # gives all gems' dependencies
