Rails 无法在生产环境中加载（404 错误）CSS 和 JS 文件，但在开发环境中加载它们没有问题。

我正在使用 Capistrano 进行部署和运行 Rails 3。我的开发路径是/www/myapp但我的生产路径是/www/myapp/current。

应用程序本身似乎工作正常，因此问题似乎与 CSS/JS 文件无关。

我尝试在environment/production.rb中将RAILS_ROOT变量设置为/www/myapp/current但它没有任何区别，文件仍然没有加载。

这是生产日志的完整堆栈：

错误消息看起来像您的 Rails 应用程序正在获取对静态文件的请求。Rails 3 默认不提供静态文件，因为网络服务器可以做得更好。您应该检查您的网络服务器的配置。它应该配置为首先查看请求的公共目录中是否存在静态文件，如果没有静态文件，则仅将请求转发到 Rails 应用程序。

或者，您可以启用 Rails 以config.serve_static_assets = true在 config/environments/production.rb 中提供静态文件。但是，不建议在生产环境中这样做，因为您真的不应该仅仅为了提供静态文件而浪费 Rails 应用程序的处理资源。最好告诉网络服务器这样做。

我通过运行以下命令解决了这个问题：

RAILS_ENV=production rake assets:precompile

参考： http: //guides.rubyonrails.org/asset_pipeline.html

My environment is Nginx + Unicorn + Rails4
