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： @H_502_2@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

@H_502_2@//= require jquery //= require jquery_ujs //= require js-routes //= require bootstrap //= require_tree . //= require bootstrap-slider

application.css.scss

@H_502_2@*= require jquery.ui.core *= require jquery.ui.theme *= require_self *= require bootstrap-slider *= require_tree . *= stub active_admin */ @import "bootstrap";

的Gemfile
