Rails 4 + Bootstrap设置资产 [英] Rails 4 + bootstrap set up assets

问题描述

我试图使用 bootstrap-sass 在 Rails4 上设置 bootstrap ，但出现此著名错误：

I am trying to setup bootstrap on Rails4 using bootstrap-sass and I am getting this famous error:

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

我尝试了以下操作：

1. twitter / bootstrap 在 application.js
中b $ b
2. gem'bootstrap-sass'，'〜> 3.1.0'在组外资产


3. 也尝试在互联网上进行其他操作

1. twitter/bootstrap in application.js
2. gem 'bootstrap-sass', '~> 3.1.0' is outside group assets
3. Also tried bunch of other things on internet

我花了很多时间接受其他帖子的不同建议。我如何系统地调试它，如何设置bootstrap-sass？

I have spend lot of time taking different suggestions from other posts. How do I systematically debug this , how to setup bootstrap-sass ?

ps：
一直试图让 twitter-bootstrap-rails 工作顺利。

这里有一些文件

application.js

application.js

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

application.css.scss

application.css.scss

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

@import "bootstrap";

推荐答案

安装Bootstrap Gem

1。）添加引导宝石：

gem 'bootstrap-sass'

2。）了解Application.css文件
app / assets / stylesheets / application.css

2.) Understand The Application.css File app/assets/stylesheets/application.css

Application.css提取 / stylesheets 目录中的所有其他文件，并在运行应用程序时将它们合并。

Application.css takes all the other files in your /stylesheets directory and combines them for when you run your app.

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

3.) Create a New SCSS File (app/assets/stylesheets/bootstrap_and_customization.css.scss)

@import 'bootstrap';

4。）需要Bootstrap的JavaScript

4.) Require Bootstrap's JavaScript

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

5。） Rails资产

group :production do
  gem 'rails_12factor'
end

6。）捆绑安装和安装；重新启动服务器

6.) Bundle Install & Restart Server

就是这样！
