rspec 总是返回错误

Question

我运行：

$ bundle exec rspec spec/

并收到此消息：

C:/RailsInstaller/Ruby1.9.2/lib/ruby/gems/1.9.1/gems/rspec-core-2.0.1/lib/rspec/core.rb:78:in `require': no such file to load -- rspec/expectations (LoadError)

from C:/RailsInstaller/Ruby1.9.2/lib/ruby/gems/1.9.1/bin/rspec:19:in `<main>'

在我的 Gemfile 中：

group :development do
gem 'rspec-core', '2.0.1'
gem 'annotate', :git => 'git://github.com/ctran/annotate_models.git'
end

我需要做什么才能运行 rspec？

Answer 1

rspec-rails，它安装核心以及 rspec 所需的其他内容。
