rails3程序部署产品模式之后
出现以下静态文件错误

17:14:26 INFO: Started GET "/assets/application-b42d228d39a3e30c7479d7bf2fd1709b.js" for 10.0.2.2 at 2013-03-07 17:14:26 +0800 
17:14:26 FATAL: 
ActionController::RoutingError (No route matches [GET] "/assets/application-b42d228d39a3e30c7479d7bf2fd1709b.js"):

  railties (3.2.9) lib/rails/rack/logger.rb:32:in `call_app'
  railties (3.2.9) lib/rails/rack/logger.rb:18:in `call'

这个问题看上去像是assert资源的问题，首先要确保下面这个命令运行，编译静态文件

bundle exec rake assets:precompile

我上面处先的问题是在这一步之后，我的启动方式，是

rails s

开发模式样式表，js什么的都有，但是产品模式下就是上面那个问题了。

原因在下面：

# config/environments/production.rb
...
config.serve_static_assets = false
...

上面是产品模式的配置，开发模式默认是没有这个选项的。

解决方案有两种：
方法一：是把上面那一行配置改成 true
方法二：是搭建nginx或者apache服务器，ngxin和apache会直接读取静态文件，不会产生这个问题

这是来自stackoverflow上的答案

In production mode, Rails will not be responsible for serving static assets. Therefore, you are getting this error. Thin won't do it either, since it's just a wrapper around Rails.

This is controlled by this setting in config/environment/production.rb in your application:

config.serve_static_assets = false
You can either set to that true or use a real server like Apache or Nginx which will serve the static assets. I suspect Pow may also do it.
