【问题描述】：

在使用 webrick 在生产模式下运行的本地计算机（即rails s -e production）上，我使用RAILS_ENV=production bundle exec rake assets:precompile 生成了css，它创建了application-d2bcfd35ef1c0c30b7a7ca94e52c0cbd.css，布局文件也引用了它。

但是在加载页面时出现错误：

Started GET "/assets/application-d2bcfd35ef1c0c30b7a7ca94e52c0cbd.css" for 127.0.0.1 at 2011-11-02 10:12:55 +0000

我阅读了配置导轨指南：

config.serve_static_assets 将 Rails 本身配置为提供静态服务资产。默认为true，但在生产环境中开启关闭作为用于运行的服务器软件（例如 Nginx 或 Apache）应用程序应该提供静态资产。与默认不同在运行时将其设置为 true（绝对不推荐！）或使用 WEBrick 在生产模式下测试您的应用程序。否则你不会能够使用页面缓存和对定期存在的文件的请求在公共目录下无论如何都会点击你的 Rails 应用程序。

因此，将 config.serve_static_assets 更改为 true for production.rb 会正确引用文件。有没有办法配置 webrick 来提供资产管道文件？或者是否有任何其他易于设置的 Rails 服务器，以便我的开发机器在生产模式下运行？

我正在使用 Apache Web 服务器在 Mac OS 10.6 (Snow Leopard) 上运行。

【问题讨论】：

为什么要在开发环境中预编译资产？
您能否更具体地说明错误发生的确切时间：在本地以开发模式运行时、在本地以生产模式运行时或在服务器上以生产模式运行时？您能否添加（针对问题）关于您希望在生产模式下运行应用程序的机器（Linux、Windows、...）的信息？
@MarekTihkan - 我想在本地机器上预编译我的资产，这样我就可以设置生产环境而无需实际部署到生产环境
@mliebelt - 我正在尝试在本地机器上设置生产环境。我已使用此信息更新了问题。

【解决方案1】：

您可以为Vagrant (RailsCasts episode) 克隆您的生产环境，这将使开发机器上的生产环境测试更加真实。

或

您可以创建新环境来测试生产设置并将config.serve_static_assets 标记为true。

或

您可以尝试使用其他服务器，例如thin...

可能第一个会给你最精确的结果，它是如何在生产中工作的，你不会在生产中使用 Webrick 或 Thin。
