試圖建立一個新的鐵路項目，但由於一些奇怪的原因，我無法得到我的RSpec安裝。它不斷拋出以下錯誤：
c700595:retro deh0002a$ bundle exec rails generate rspec:install
Could not find rspec-support-3.0.4 in any of the sources
Run `bundle install` to install missing gems.
這是我的Gemfile看起來是這樣的：
source 'https://rubygems.org'
# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.1.6'
# Use postgresql as the database for Active Record
gem 'pg'
# Use SCSS for stylesheets
gem 'sass-rails', '~> 4.0.3'
# Use Uglifier as compressor for JavaScript assets
gem 'uglifier', '>= 1.3.0'
# Use CoffeeScript for .js.coffee assets and views
gem 'coffee-rails', '~> 4.0.0'
# See https://github.com/sstephenson/execjs#readme for more supported runtimes
# gem 'therubyracer', platforms: :ruby
# Use jquery as the JavaScript library
gem 'jquery-rails'
# Turbolinks makes following links in your web application faster. Read more: https://github.com/rails/turbolinks
gem 'turbolinks'
# Build JSON APIs with ease. Read more: https://github.com/rails/jbuilder
gem 'jbuilder', '~> 2.0'
# bundle exec rake doc:rails generates the API under doc/api.
gem 'sdoc', '~> 0.4.0', group: :doc
# Spring speeds up development by keeping your application running in the background. Read more: https://github.com/rails/spring
gem 'spring', group: :development
# Use ActiveModel has_secure_password
gem 'bcrypt', '~> 3.1.7'
# Use unicorn as the app server
# gem 'unicorn'
# Use Capistrano for deployment
# gem 'capistrano-rails', group: :development
# Use debugger
# gem 'debugger', group: [:development, :test]
group :development, :test do
gem 'rspec-rails', '~> 3.0.0'
end
我已經運行了捆綁安裝命令的錯誤提示：

Your bundle is complete!
Use `bundle show [gemname]` to see where a bundled gem is installed.
所以從我的捆綁器輸出中，缺失的寶石實際上就在那裏。 有人可以告訴我我在這種情況下實際上失蹤了嗎？
