Ruby on rails 生产模式中的Authlogic问题：未定义的局部变量或方法'acts'u as_authentic'；对于类名

我正在rails应用程序中使用AuthLogic gem。它在开发环境中工作正常，但当我切换到生产环境时，会出现一个错误，阻止应用程序启动：

/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'

        from ./public/dispatch.fcgi:21

我正在使用authlogic（2.1.5）和rails（2.3.8）

该错误仅在生产环境中发生，即使我的生产环境和开发数据库是相同的。本地主机上的问题与web服务器上的问题相同。我真的很感激能得到任何帮助。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。它被冻结在我的申请表中。我不确定如何验证它的安装方式是否适合我运行web服务器的用户。以下是rake gems RAILS_ENV=production的输出：

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)

我尝试解冻gem，但得到了相同的错误。

authlogic gem是安装在您的生产环境中还是冻结在您的应用程序中？另外，它的安装方式是否允许您运行web服务器的用户使用？（如果您已检查此项，则表示歉意，但从头开始是有意义的）

---

最后，值得检查的是，您的

config.gem“authlogic”

在environment.rb中的调用是否在使用您的

Book

类之前，该类似乎导致了问题。

rake gems RAILS_ENV=production的输出是什么？
