Bootstrap 样式未应用于 Rails 页面

Question

我是 Rails 的新手，所以一直在关注构建项目的在线视频教程。

我一直在尝试添加 Bootstrap，但即使在

之后

1. 添加 Gem,
2. 进行捆绑安装，
3. 正在重新启动 mysql 服务器，并且
4. 将 scss @bootsrap 导入添加到 application.css.scss 文件，

它仍然没有拉到我的索引页。

有什么我想念的吗？

这是我的 application.css.scss

/*
 * This is a manifest file that'll be compiled into application.css, which will include all the files
 * listed below.
 *
 * Any CSS and SCSS file within this directory, lib/assets/stylesheets, vendor/assets/stylesheets,
 * or any plugin's vendor/assets/stylesheets directory can be referenced here using a relative path.
 *
 * You're free to add application-wide styles to this file and they'll appear at the bottom of the
 * compiled file so the styles you add here take precedence over styles defined in any styles
 * defined in the other CSS/SCSS files in this directory. It is generally better to create a new
 * file per style scope.
 *
 *= require_self
 */
// Custom bootstrap variables must be set or imported before bootstrap itself.
@import "bootstrap-sprockets";
@import "bootstrap";

这是我的 gem 文件：

source 'https://rubygems.org'

gem 'rails', '4.2.6'
gem 'sqlite3'
gem 'simple_form', '>= 3.2.1'
gem 'bootstrap-sass', '~> 3.3.6'
gem 'sass-rails', '>= 3.2'
gem 'uglifier', '>= 1.3.0'
gem 'coffee-rails', '~> 4.1.0'
gem 'jquery-rails'
gem 'turbolinks'
gem 'jbuilder', '~> 2.0'
gem 'sdoc', '~> 0.4.0', group: :doc

group :development, :test do
  gem 'byebug'
end

group :development do
  gem 'web-console', '~> 2.0'
end

gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw, :jruby]

谢谢！

请加入你的application.html.erb

<%= stylesheet_link_tag    'application', media: 'all', 'data-turbolinks-track' => true %>
<%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>

并添加您的 application.css

@import "bootstrap-sprockets";
@import "bootstrap";
@import 'bootstrap/theme';
