升级 Shoulda gem 会导致 RSpec 和 Ruby on Rails 出错

Question

将我的 shoulda gem 升级到 3.4.0 后，我的测试将不再运行。

上下文：

• Ruby 1.9.3-p392
• Rails 3.2.12
• Rspec 2.13.0 Mac
• OS X 10.8.3

当我设置我的 Gemfile 并运行 bundle exec rspec spec 时，我收到以下错误：

#Gemfile #1
group :test do
  gem 'rspec-rails', '2.13.0'
  gem 'shoulda', '3.4.0'
end

错误：gems/activesupport-3.2.13/lib/active_support/dependencies.rb:251:in `require': cannot load such file -- rspec (LoadError)

#Gemfile #2
group :test do
  gem 'factory_girl_rails', '4.2.1'
  gem 'rspec-rails', '2.13.0'
  gem 'shoulda-matchers', '1.5.0'
end

错误：gems/activesupport-3.2.13/lib/active_support/dependencies.rb:251:in `require': cannot load such file -- rspec (LoadError)

#Gemfile #3 
group :test do
  gem 'factory_girl_rails', '4.2.1' 
  gem 'rspec', '2.13.0'
  gem 'shoulda', '3.4.0'
end

错误：/gems/activesupport-3.2.13/lib/active_support/dependencies.rb:251:in `require': cannot load such file -- rspec/rails (LoadError)

这些是唯一有效的 Gemfile 版本，但它们似乎不是正确的设置：

#Gemfile #4
group :test do
  gem 'factory_girl_rails', '4.2.1'
  gem 'rspec', '2.13.0'
  gem 'rspec-rails', '2.13.0'
  gem 'shoulda-matchers', '1.5.0'
end

#Gemfile #5
group :test do
  gem 'factory_girl_rails', '4.2.1'
  gem 'rspec', '2.13.0'
  gem 'rspec-rails', '2.13.0'
  gem 'shoulda', '3.4.0'
end

Answer 1

将 shoulda-matchers 升级到 1.5.4 并将 gem 组更改为 开发和测试

从 1.5.X 到 1.5.4 有一个回归。我遇到了同样的问题。
