我有这样的课

class RecurringJob
  include ScheduledJob

  run_every 1.hours

  def perform
    puts "perform job"
  end
end

我收到一条错误消息：

预期 D:/ASM/source/app/lib/jobs/scheduled_job.rb 来定义 ScheduledJob

文件定义是这样的：

module Delayed
 module ScheduledJob

def self.included(base)
  base.extend(ClassMethods)
  base.class_eval do
    @@logger = Delayed::Worker.logger
    cattr_reader :logger
  end
end
    ....

 end
end

错误是什么意思？这不是一个定义吗？

编辑

我你必须知道，这个类是在一个 rake 任务中定义的（除了这个类之外它是空的，我不知道这是否允许）。

更详细的错误：

Rails 遵循非常严格的命名约定，其中包括 lib 文件。

如果要在 Delayed 模块中定义 ScheduledJob 模块，则必须将文件命名为/lib/delayed/scheduled_job.rb

这将使 Rails 的期望和你的命名相匹配。
