应用程序不会在config.cache_classes设置为true的生产模式下启动。它在stacktrace中给出以下错误：

奇怪的是，它可以在缓存关闭时正常工作。我的production.rb文件看起来像
App::Application.configure do
config.cache_classes = true
config.consider_all_requests_local = false
config.action_controller.perform_caching = true
config.action_dispatch.x_sendfile_header = "X-Sendfile"
config.action_mailer.delivery_method = :sendmail
config.action_mailer.perform_deliveries = true
config.action_mailer.raise_delivery_errors = true
config.serve_static_assets = false
config.i18n.fallbacks = true
config.active_support.deprecation = :notify
config.action_dispatch.best_standards_support = :builtin
end
我正在使用以下宝石：
source 'http://rubygems.org'
gem 'rails', '3.0.7'
gem 'mysql2', '0.2.1'
gem 'carrierwave'
gem 'rmagick'
gem "capistrano-ext"
gem 'rake', '0.8.7'
group :development do
gem 'rspec-rails', '2.1.0'
gem 'ruby-debug19'
gem 'wirble'
end
group :test do
gem 'ruby-debug19'
gem 'rspec', '2.1.0'
gem 'webrat', '0.7.1'
gem 'factory_girl_rails', '1.0'
end
gem 'thinking-sphinx', '2.0.3'
我非常感谢任何帮助

我知道，我做了一些愚蠢的事情（虽然不是我所有的，同样的旧设计师故事。我应该检查git提交）。我在app目录和项目目录中都有spec文件夹。但我仍然感到困惑，为什么它与
一起使用config.cache_classes = false
在production.rb。
