Question

我在我的rails应用程序中使用AuthLogic gem。它在开发环境中工作正常但是当我切换到生产环境时，我收到一个错误，导致应用无法启动：

/home/.../rails/xxx/app/models/book.rb:2: undefined local variable or method `acts_as_authentic' for Book:Class (NameError)
        from /usr/lib64/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require'

我正在使用authlogic（2.1.5）和rails（2.3.8）

错误只发生在生产环境中，即使我的生产和dev DB是相同的。 localhost与Web服务器上的问题相同。我真的很感激我能得到的任何帮助。如果需要更多信息，请告诉我。非常感谢！

9月15日编辑： 谢谢你的回复。它被冻结在我的应用程序中。我不确定如何验证它是否以我运行我的Web服务器的用户可用的方式安装。这是rake gems的输出RAILS_ENV = production：

rake gems RAILS_ENV=production
(in /Users/my_user_name/Sites/my_app_name)
 - [F] authlogic 
    - [R] activesupport 
 - [F] acts-as-taggable-on = 2.0.0.rc1
 - [R] rails 
 - [F] will_paginate 
 - [I] nokogiri 

I = Installed
F = Frozen
R = Framework (loaded before rails starts)

9月17日编辑： 我尝试解冻宝石并得到同样的错误。

authlogic gem是在您的生产环境中安装还是冻结在您的应用程序中？此外，它是否以您运行Web服务器的用户可用的方式安装？（如果您已经检查了这一点，请道歉，但从一开始就有意义）

最后，值得检查一下，环境.rb中的config.gem "authlogic"调用是否在使用Book类之前，这似乎是导致问题的原因。

生产模式中的Authlogic问题：未定义的局部变量或类名称的“acts_as_authentic”方法
