ruby-on-rails – Rails 4引导设置资产

我正在尝试使用bootstrap-sass在Rails4上设置引导,我得到这个着名的错误：

Sprockets::FileNotFound - couldn't find file 'bootstrap'
  (in app/assets/javascripts/application.js:16):

我试过以下：

> application.js中的twitter / bootstrap
> gem’bootstrap-sass’,’〜> 3.1.0“是集团外资产
>还试过一堆互联网上的其他东西

我花了很多时间从其他帖子中获得不同的建议.如何系统地调试这个,如何设置bootstrap-sass？

P.S：
也试图让twitter-bootstrap-rails工作没有运气.

这里有一些文件

的application.js

//= require jquery
//= require jquery_ujs
//= require js-routes
//= require bootstrap
//= require_tree .
//= require bootstrap-slider

application.css.scss

*= require jquery.ui.core
 *= require jquery.ui.theme
 *= require_self
 *= require bootstrap-slider
 *= require_tree .
 *= stub active_admin
*/

@import "bootstrap";

解决方法

安装引导宝石

1.)添加引导宝石：

gem 'bootstrap-sass'

2.)了解Application.css文件
应用程序/资产/样式表/ application.css

Application.css将所有其他文件放在/ stylesheets目录中,并在运行应用程序时进行组合.

3.)创建一个新的SCSS文件(app / assets / stylesheets / bootstrap_and_customization.css.scss)

@import 'bootstrap';

4.)需要Bootstrap的JavaScript

...
//= require jquery
//= require jquery_ujs
//= require bootstrap <--
//= require turbolinks
//= require_tree .

路轨资产

group :production do
  gem 'rails_12factor'
end

6.捆绑安装&重新启动服务器

这应该是！
