在rails 4上使用Sprockets的application.js中找不到文件错误

Question

您好我在Rails 4.1.5

上收到了错误Sprockets::FileNotFound: couldn't find file 'jquery-fileupload/basic.js'

我搜索了一些相关的问题，但找不到解决方案。

的application.js

//= require jquery
//= require jquery-ui
//= require jquery_ujs
//= require twitter/bootstrap
//= require jquery-fileupload/basic
//= require jquery-fileupload/vendor/tmpl

我使用rbenv并且gem /jquery-fileupload-rails-0.4.1结构是

〜/ .rbenv /版本/ 2.1.2 / LIB /红宝石/宝石/ 2.1.0 /宝石/ jQuery的文件上传-导轨-0.4.1 /供应商/资产/ Javascript角

.

    ├── basic.js

        └── tmpl.js

当我跑rake assets:precompile --trace

时

我收到以下错误消息
