我用一个带有索引功能的简单页面控制器制作了一个基本的Rails应用程序，当我加载页面时，我得到了:
I made a basic rails app with a simple pages controller with an index function and when I load the page I get:
ActionView::Template::Error (application.css isn't precompiled):

4: <title>Demo</title>
5: <%= stylesheet_link_tag "application" %>

推荐答案
默认情况下，Rails假定您已经在生产环境中对文件进行了预编译，如果要在生产中使用实时编译(在运行时编译资产)，则必须设置 config.assets.compile为true .
By default Rails assumes that you have your files precompiled in the production environment, if you want use live compiling (compile your assets during runtime) in production you must set the config.assets.compile to true.
# config/environments/production.rb
...
config.assets.compile = true
...
使用预编译资产时，您可以使用此选项回退到Sprockets，但是缺少任何预编译文件.
You can use this option to fallback to Sprockets when you are using precompiled assets but there are any missing precompiled files.
如果config.assets.compile选项设置为false并且缺少预编译的文件，您将收到一个"AssetNoPrecompiledError"，指示丢失的文件的名称.
If config.assets.compile option is set to false and there are missing precompiled files you will get an "AssetNoPrecompiledError" indicating the name of the missing file.
