Twitter-bootstrap-rails：它是否将Bootstrap安装到项目中？

Question

我根据Readme一切，但有一个问题开始做一个Rails应用程序时：链轮:: FileNotFound并将其指向//= require twitter/bootstrap这是否真的宝石安装引导样式表和相应的JS库或者一个应该手动安装（与凉亭或以另一种方式）？ 这里是我的Gemfile：

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails' 
gem 'rails', '4.2.5.1' 
# Use postgresql as the database for Active Record 
gem 'pg', '~> 0.15' 
# Use SCSS for stylesheets 
gem 'sass-rails', '~> 5.0' 
# Use Uglifier as compressor for JavaScript assets 
gem 'uglifier', '>= 1.3.0' 
# 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 

# 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 
group :assets do 
    gem 'twitter-bootstrap-rails' 
end 

gem 'responders', '~> 2.1.1' 
gem 'haml' 

group :development, :test do 
    gem 'pry-byebug' 
    gem 'pry-rails' 
    gem 'rspec-expectations', '~> 3.0.0' 
    gem 'spring-commands-rspec' 
    #gem 'guard-rspec', require: false 
    gem 'rspec-rails', '~> 3.0.0' 
    # Support for its syntax 
    gem 'rspec-its', '~> 1.0.1' 
    gem 'shoulda-matchers', '~> 3.1.1' 
    gem 'factory_girl_rails' 
    gem 'ffaker' 
    gem "bower-rails", "~> 0.10.0" 
end 

group :development do 
    # Access an IRB console on exception pages or by using <%= console %> in views 
    gem 'web-console', '~> 2.0' 
    gem 'haml-rails' 
    # Spring speeds up development by keeping your application running in the background. Read more: https://github.com/rails/spring 
    gem 'spring' 
end

我会说，因为group assets were dropped in Rails 4。从文档：

Rails 4.0从Gemfile中删除资产组。升级时需要从Gemfile中删除该行。你也应该更新您的应用程序文件（在配置/ application.rb中）：

因此，而不是使用它的

.... 
# Use Capistrano for deployment 
# gem 'capistrano-rails', group: :development 
group :assets do 
    gem 'twitter-bootstrap-rails' 
end 
.... 

只需卸下group块：

.... 
# Use Capistrano for deployment 
# gem 'capistrano-rails', group: :development 
gem 'twitter-bootstrap-rails' 
.... 

然后运行bundle install并重新启动服务器。
