Ruby on rails 为什么赢了'；t print.scss在Heroku上加载罗盘/重置？

在localhost上，Compass可以完美地工作<代码>屏幕。scss加载

compass/reset

很好。

print.scss

也是如此

在Heroku上，screen.scss仍然有效，但是

print.scss

给出了以下错误：

Error compiling CSS asset
Sass::SyntaxError: File to import not found or unreadable: compass/reset.
Load path: Sass::Rails::Importer(/app/app/assets/stylesheets/print.scss)
(in /app/app/assets/stylesheets/print.scss)
/app/app/assets/stylesheets/print.scss:1

为什么?？我怎么修理它

/app/views/reviews/print.html（根据

print.html.haml

编译）：

在博客上找到答案：

默认情况下，Rails只预编译application.css。如果你有 额外的样式表，比如ie.css或print.css，它们不会 除非您明确地告诉Rails这样做，否则必须进行预编译

config.assets.precompile+=['ie.css'，'print.css']

在部署到heroku之前，您没有在本地预编译您的资产有什么原因吗？因为（a）没有预编译似乎没有给我带来任何问题，（b）预编译在/public/中放置了一堆预编译的资产，当我在localhost上查看我的应用时，这些资产与/asset/中的资产发生了冲突。你认为这可能是问题所在吗？
