如何实现Bootstrap 4和Rails 5 [英] how to implement bootstrap 4 and rails 5

问题描述

我是红宝石的新手，我正在尝试将Bootstrap 4.0.0.alpha4包含在rails 5.0.0中。
我已经安装了gems bootstrap，bootstrap-sass，autoprefixer-rails，甚至在application.css.sass中使用了@import bootstrap，但仍然无法在页面上获取bootstrap。我尝试实现引导程序设计的视图上的按钮。我什至在不同的项目上都尝试过，但都不起作用。任何帮助，将不胜感激。谢谢。

代码如下所示。

I am new to ruby and I am trying to include bootstrap 4.0.0.alpha4 into rails 5.0.0. I have installed the gems bootstrap,bootstrap-sass, autoprefixer-rails and I have even used @import "bootstrap" in the application.css.sass, but still I am not getting the bootstrap on the page.I have a button on the view where I am trying to implement the bootstrap design. I have even tried it on different projects ut none of them works. Any help would be appreciated. Thanks.

很好链接和
这是我的配置：

Great link and here is my config:

Gemfile：

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'

config / initializers / assets.rb

config/initializers/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：

And on my sass files tree:

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：

bootstrap.sass:

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

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

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