延迟作业轨道 3 未定义的方法'up'

Question

我试图从几个月前使用Rails 3.0.7复活一个项目。

我之前推迟了工作，但现在我更新了我的宝石，当我尝试和enqueue一些东西时，我得到以下错误。

NoMethodError (undefined method up' for:null:Symbol): '

这行代码是:

Delayed::Job.enqueue DelayedXlsExport.new(@email, timestamp, filename)

DelayedXlsExport是:

class DelayedXlsExport < Struct.new(:email, :timestamp, :filename)  
  def perform
    ....
  end
end

这是堆栈的一部分:

My gem file:

gem "delayed_job", :branch => 'v2.1', :git => 'git://github.com/collectiveidea/delayed_job.git'

有什么想法吗?
