Question

我正在使用rubygem延迟作业但无法成功运行rake任务。我参考了https://github.com/collectiveidea/delayed_job/tree/v2.0。顺便说一句，我正在使用捆绑包。

#Gemfile
gem 'delayed_job', '~>2.0.4'

#Rake file
begin
  gem 'delayed_job', '~>2.0.4'
  require 'delayed/tasks'
rescue LoadError
  STDERR.puts "Run `bundle` to install delayed_job"
end

在运行rake jobs:work --trace时，它会显示以下错误

rake/rdoctask is deprecated.  Use rdoc/task instead (in RDoc 2.4.2+)
** Invoke jobs:work (first_time)
** Invoke merb_env (first_time)
** Execute merb_env
** Invoke environment (first_time)
** Execute environment
** Execute jobs:work
rake aborted!

Tasks: TOP => jobs:work

我试过Delayed Job Rake Task Failing，但它没有解决我的问题。

有人能描述这里发生了什么吗？感谢。

Answer 1

啊！调试DJ是一个痛苦的你知道什么。

此错误消息：

=> Aonymous modules have no name to be referenced by

表示您拼错了其中一个模型。

例如：Categorizatoin而不是Categorizatoin。

请仔细阅读DJ中的模特并检查所有模特的拼写。

Answer 2

我真的不明白为什么DJ无法在2.3版本的rails版本中正常使用gem。确保你已经安装了插件而不是gem，然后按照文档说的那样做。我希望这不会给你anonymous module问题。

使用rails 2.3.5延迟了作业的任务问题
