请教一下关于rails assets precompile问题

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.ymlStarted GET "/" for 112.226.204.86 at 2013-06-03 22:24:47 +0800Processing by DiscussionsController#index as HTML  Rendered collection (0.0ms)  Rendered discussions/_discussions.html.erb (0.8ms)  Rendered discussions/index.html.erb within layouts/application (18.0ms)Completed 500 Internal Server Error in 128msActionView::Template::Error (application.css isn't precompiled):    3:     4:   <%= full_title(yield(:title)) %>    5:       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

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
