“config.cache_classes = true”没有要加载的文件 -/path-to-app/app/config/environment（LoadError）

应用程序无法在config.cache_classes设置为true的生产模式下启动。它给堆栈跟踪带来以下错误：“config.cache_classes = true”没有要加载的文件 -/path-to-app/app/config/environment（LoadError）

奇怪的是，它可以在缓存关闭时正常工作。我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

我使用下面的宝石：

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'

我真的很感激

如果您尝试“rails s -e production”，您得到了什么？ – Awea

我得到了同样的结果，问题以任何方式解决。你仍然可以帮忙。看看我的答案。 –

我知道，我是在做一些愚蠢的任何帮助（虽然它并不是我所有的，同样的老设计师的故事。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。但我仍然困惑，为什么它可以与

config.cache_classes = false

in the production.rb。
