Ruby on rails 提供未定义方法错误的延迟作业

Delayed job（2.1.4）在我的开发机器上运行得很好，发送电子邮件时毫不留情，但在使用Apache/Passenger（3.0.7）的服务器上运行时，它却失败得很惨。顺便说一句，Rails 3.0.7和ruby 1.9.2都在这两个平台上

我已经看到，在创建作业时，使用thin会出现如下问题：

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

何时应改为：

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

在我的开发机器上正确地创建了我的，但在服务器上创建时的方式是错误的

还有其他人有这个问题吗？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\u load\u paths.rb。这意味着gemfile被加载到了所有地方，除了乘客。这打乱了对YAML:：ENGINE.yamler=“syck”的调用，这似乎破坏了对象的保存

---

我删除了设置加载路径，现在一切都很好。

如果使用Syck解析器似乎不起作用（如Marc的回答中所述），请尝试使用psych解析器

YAML::ENGINE.yamler = "psych"

我不知道为什么创建作业的方式会有所不同（可能是因为类在dev中被吹走和重新加载的方式），但您实际会遇到什么错误？您是否尝试在“生产”模式下本地运行？可能会发布stacktrace。我在从3.0.6升级到3.0.9 Rails.3.0.6（使用1.9.2）时遇到问题工作正常。我的解决方案是在处理程序类中重新定义“taguri”函数。我已经调试这个问题很长一段时间了，然后偶然发现了这个问题！太棒了！但是这个设置\u load\u path.rb有什么作用？我没有它，但仍然遇到这个问题。其中有什么？
