Question

我正在使用jruby（1.7.3或1.7.9），delayed_job（1.8.4），守护进程（1.1.9）宝石用于我的rails 2.3.17应用程序。

我正在尝试使用命令启动延迟的作业服务器： 1. jruby script / delayed_job start

错误：

RuntimeError: ObjectSpace is disabled; each_object will only work with Class, pass -X+O to enable
  each_object at org/jruby/RubyObjectSpace.java:173
    daemonize at /home/user/projects/new_central_repo/mml/mml_services/vendor/gems/delayed_job-1.8.4/lib/delayed/command.rb:39
       (root) at script/delayed_job:5

要解决此错误，我通过了“-X + O”选项＆amp;运行以下命令： jruby -X + O script / delayed_job start

这已解决“ObjectSpace已禁用”错误，但我在本地遇到以下错误。错误：

任何人都可以帮我解决此错误。

本地我可以使用“jrake jobs：work”命令启动我的服务器，但我不是能否使用“jrake jobs：work”而不是“jruby script / delayed_job start”。

感谢。

你不能在jruby上使用delayed_job，因为它依赖于在jruby中没有的Fork。

delayed_job gem - NotImplementedError：此平台上没有fork
