我用的 nginx+unicorn
访问网站会出现 We're sorry, but something went wrong.
我看了一下 production.log

Connecting to database specified by database.yml
Started GET "/" for 112.226.204.86 at 2013-06-03 22:24:47 +0800

  Rendered discussions/_discussions.html.erb (0.8ms)
  Rendered discussions/index.html.erb within layouts/application (18.0ms)
Completed 500 Internal Server Error in 128ms

ActionView::Template::Error (application.css isn't precompiled):
    3: <head>
    4:   <title><%= full_title(yield(:title)) %></title>
    5:   <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
    6:   <%= stylesheet_link_tag    "application", :media => "all" %>
    7:   <%= stylesheet_link_tag    "home", :media => "all" %>
    8:   <%= javascript_include_tag "application" %>
    9:   <%= csrf_meta_tags %>
  app/views/layouts/application.html.erb:6:in `_app_views_layouts_application_html_erb___881267949553662586_30659220'

然后根据 stackoverflow 上说的设置了 config.assets.compile = true 重启了 unicorn 依然还是上面的情况
最后 rake assets:precompile 又报出一些错误

/usr/bin/ruby1.9.1 /usr/local/bin/rake assets:precompile:all RAILS_ENV=production RAILS_GROUPS=assets
rake aborted!

实在是有点晕
还有实验了 config.assets.precompile += %w( application.css ) 和 config.assets.precompile += %w( application.js ) 还是不可以 -.-!
麻烦各位帮忙看看 谢谢

部署之前需要先 rake assets:precompile 具体请详细看一下 Rails Assets Pipline 的 Guide
