我有一个在开发中运行良好的 Rails 应用程序。我正在RubyMine中开发它，但我使用Webrick和sqlite3从终端测试和运行它（文件存储/运行在我通过OSX终端访问的Ubuntu工作站上）。该应用程序使用修改后的 Boostrap 模板，并且运行良好。现在我想尝试在生产模式下运行它。
这就是我所做的：Rails 版本是 3.2.11，我使用 rvm 1.8.1 和 ruby-1.9.2-p290
config.logger = Logger.new(STDOUT) in environment/production.rb
config.serve_static_assets = true in environment/production.rb
export RAILS_ENV=production
rake db:migrate (works fine)
rake assets:precompile --trace
我收到以下错误：

现在，如果我在一个干净的 Rails 应用程序上执行上述操作，它就可以工作。但它在我认为有效的应用程序上失败了。你能指出什么是错的吗？
_form.rb 是带有 simple_form 调用的部分，没有什么特别的。
（此处仅显示两行以显示错误似乎发生的位置）
<%= yield :title %>
<%= simple_form_for(@article, :html => {:multipart => true, :class => 'form-horizontal'} ) do |ff| %>
任何帮助表示赞赏！
