延迟作业给出未定义的方法错误

Question

延迟作业(2.1.4)在我的开发机器上完美运行,发送同性恋放弃的电子邮件 - 但是当使用Apache/Passenger(3.0.7)在我的服务器上运行时,它失败了.两个顺便说一下Rails 3.0.7和ruby 1.9.2.

我已经看到在使用thin创建作业时出现问题:

--- !ruby/struct:Delayed::PerformableMailer
object: !ruby/object:Class UserMailer

什么时候应该读:

--- !ruby/struct:Delayed::PerformableMailer
object: !ruby/class UserMailer 

我的开发机器上正确创建了我的,但在服务器上创建时却是错误的.

有没有其他人有这个问题,我应该从哪里开始寻找？

我已经设法解决这个问题。

几周前，当捆绑程序由于某种原因停止工作时，我创建了一个 setup_load_paths.rb 。这意味着除了乘客之外，gemfile 正在被任何地方加载。这搞乱了对 YAML::ENGINE.yamler = "syck" 的调用，这似乎是破坏对象保存的原因。

我删除了 setup_load_paths，现在一切正常。
