rspec的它总是返回错误

Question

我运行：

$ bundle exec rspec spec/ 

收到该消息：

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：

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

需要什么条件才能运行做RSpec的？

rspec-rails，它安装核心和rspec所需的其他内核。
