我在 rails 4 中构建了一个可安装的 rails 引擎。我在另一个应用程序中使用了该引擎。在开发模式下，一切运行正常，我可以毫无问题地使用引擎，并且所有引擎资产都正确显示。
但是当我将主机应用程序部署到我的服务器时，我的 scss 和 js 文件不再包括在内。所有引擎资产均已正确编译。在 public/assets 目录中存在一个带有引擎名称的目录，我可以找到已编译的 css 和 js 文件以及图像。
但！当我从主机应用程序中打开引擎页面时（因此呈现引擎布局文件）
<%= stylesheet_link_tag "backbone/application.css", media: "all" %>
<%= javascript_include_tag "backbone/application.js" %>
引擎布局文件中的标头标签被翻译成：
<link href="/stylesheets/backbone/backbone.css" media="all" rel="stylesheet" />
<script src="/javascripts/backbone/backbone.js"></script>.
显然，这些标签不引用资产文件夹。此外，application.js 和 application.css 被重命名为主干.js 和主干.css。
有人可以告诉我为什么在部署期间编译资产，但是应该查明资产的样式表 javascript 标签是完全错误的吗？我忘记了引擎中的一些配置吗？
