如何实现bootstrap 4和rails 5

Question

我是ruby的新手,我正在尝试将bootstrap 4.0.0.alpha4包含到rails 5.0.0中.我已经安装了gems bootstrap,bootstrap-sass,autoprefixer-rails,我甚至在application.css.sass中使用了@import"bootstrap",但我仍然没有在页面上获取引导程序.我有一个按钮查看我在哪里尝试实现bootstrap设计.我甚至在不同的项目上尝试过它们都没有用.任何帮助,将不胜感激.谢谢.
代码如下所示.宝石文件

    source 'https://rubygems.org'


# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'

很棒的链接，这是我的配置：

宝石文件：

gem 'compass-rails', '2.0.4'
gem 'bootstrap-sass', '~> 3.1.1.1'
gem 'autoprefixer-rails', '6.3.7'
gem 'sass-rails', '~> 5.0.1'

配置/初始化器/assets.rb

Rails.application.config.assets.version = '1.0'
Rails.application.config.assets.paths << Rails.root.join('app', 'assets', 'fonts')

在我的 sass 文件树上：

app/assets/stylesheets
|
|--components
|    |
|    |--variables, 
|    |--mixins and another css/sass files
|
|--bootstrap.sass
|--application.sass

应用程序.sass：

@import 'bootstrap'
@import 'components/*'

bootstrap.sass：

// Core variables and mixins
@import 'bootstrap/variables'
@import 'bootstrap/mixins'

// Reset
@import 'bootstrap/normalize'
//@import 'bootstrap/print'

// Core CSS
//@import 'bootstrap/scaffolding'

标头：

= stylesheet_link_tag 'application', media: 'all'
