css - rails 上的 ruby : stylesheet in assets doesn't works

Question

即使在阅读 http://guides.rubyonrails.org/asset_pipeline.html 之后，我的 Assets 管道也一直存在问题我仍然遇到麻烦。

当我在开发中加载我的页面时，我的 css 没有呈现，看起来 css 没有被考虑在内，因为如果我把这个 css 放入 <script></script>在我的页面 home.html.erb 的标题中，它工作得很好。

我在 app/assets/stylesheets/bootstrap.css.scss 中有这个样式表

bootstrap.css.scss

/* BOOSTRAP CSS */
/* /BOOSTRAP CSS */

.form-group {
  width: 250px;
  font-size: 10px;
  opacity: 1;
 } 


.panel {
    width:300px;
    margin-left: auto;
    margin-right: auto;
    opacity: 0.8;
    z-index: 10000;

}

.btn-default {
    border: 1px solid #28c3ab;
    color: #1abc9c;
    background-color: #f1c40f;
}




.jumbotron {
    background-color:#ecf0f1;
    color:#1abc9c;
} 

.btn-default {
    color: #1abc9c;
    background-color: #f1c40f;
}

.btn-default:hover,
.btn-default:focus {
    border: 1px solid #28c3ab;
    outline: 0;
    color: #1abc9c;
    background-color: #3498db;
}


.btn-primary {
    border: 1px solid #28c3ab;
    color: #f1c40f;
    background-color: #1abc9c;
}

.btn-primary:hover,
.btn-default:focus {
    border: 1px solid #28c3ab;
    outline: 0;
    color: #f1c40f;
    background-color: #3498db;
}

这是我在 app/assets/stylesheets/application.css 中的 application.css

/*
 * 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 vendor/assets/stylesheets of plugins, if any, 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 top of the
 * compiled file, but it's generally better to create a new file per style scope.
 *
 *= require_self
 *= require 'masonry/transitions'
 *= require_tree
 *= require font-awesome 
 *= require bootstrap
 *= require magnific-popup
 */

我不确定出了什么问题，我尝试预编译 Assets ，但仍然无法正常工作，我可能遗漏了什么？

我的布局中有指向我的样式表的链接，app/views/layouts/application.html.erb

    <%= stylesheet_link_tag "application", media: "all" %>
    <%= javascript_include_tag "application" %>
    <%= csrf_meta_tags %>

当您为生产预编译您的 Assets 时，请确保您的开发环境没有也在使用这些 Assets 。因此，请检查您的 html 并确保您可以看到每个 css 文件而不仅仅是 application.css

如果您确实发现您正在使用预编译 Assets ，请运行 rake assets:clean，然后您的开发环境将使用正确的 css 文件。
