所以我正在研究一个 gem...我输入 bundle，它会安装 rspec 2.0.1，我相信你会明白，这在 rspec 2.12.2 的这个时代是完全不可接受的。

我会同意的，除非我运行 rake spec ......

 % rake spec

Tasks: TOP => spec
(See full trace by running task with --trace)

所以这是我认为重要的部分，即使我找不到它们有什么问题：

=> 耙文件

require "bundler/gem_tasks"
require 'rspec/core/rake_task'
require 'cucumber/rake/task'

RSpec::Core::RakeTask.new(:spec)

task :default => :spec

Cucumber::Rake::Task.new(:features) do |t|
    t.cucumber_opts = "features --format progress"
end

=> 宝石文件

source :rubygems

# Specify your gem's dependencies in pipboy.gemspec
gemspec

=> 宝石规格

# -*- encoding: utf-8 -*-
lib = File.expand_path('../lib', __FILE__)
$LOAD_PATH.unshift(lib) unless $LOAD_PATH.include?(lib)
require 'pipboy/version'

Gem::Specification.new do |gem|

  gem.files         = `git ls-files`.split($/)
  gem.executables   = gem.files.grep(%r{^bin/}).map{ |f| File.basename(f) }
  gem.test_files    = gem.files.grep(%r{^(test|spec|features)/})
  gem.require_paths = ["lib"]

  gem.add_development_dependency 'rspec'
  gem.add_development_dependency 'cucumber'
  gem.add_development_dependency 'rake'
  gem.add_development_dependency 'rdoc'
end

而且，没有 Gemfile.lock，调用 bundle 的结果...

% bundle

看来，诀窍就是这样做。

gem.add_development_dependency 'rspec', '>= 2.12.0'

rspec 使用的 rspec-core 版本为 2.12.2——我错误地认为这些子宝石会与元宝石同时升级。

再说一次，我不知道为什么要下载 rspec 2.0.1 而不是 2.12.0 ...
