我跑：
$ 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)

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
为了运行rspec我需要做什么？
