ruby-on-rails - 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，发送带有同性恋放弃的电子邮件 - 但是在使用 Apache/Passenger(3.0.7) 在我的服务器上运行时它失败了。顺便说一句，Rails 3.0.7 和 ruby​​ 1.9.2。

我已经看到在使用 Thin 创建作业时存在问题，如下所示:

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

什么时候应该读:

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

我的在我的开发机器上正确创建，但在服务器上创建时以错误的方式创建。

有没有其他人遇到过这个问题，我应该从哪里开始寻找？

我已经设法解决了这个问题。

几周前，当 bundler 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 gemfile 被加载到任何地方，除了乘客。这搞砸了对 YAML::ENGINE.yamler = "syck"的调用，这似乎是破坏了对象保存的原因。

我删除了 setup_load_paths，现在一切正常。
