我正在使用jruby（1.7.3或1.7.9），delayed_job（1.8.4），守护程序（1.1.9）Gems for My 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脚本/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脚本/delayed_job start
这已经解决了" objectspace已禁用"错误，但是我在本地上遇到了遵循错误。错误：

任何人都可以帮助我解决此错误。
在本地我可以使用" jrake作业：工作"命令启动服务器，但是我不是可以使用" jrake jobs：work"而不是" jruby script/delayed_job start"。
谢谢。
您不能在jruby上使用delayed_job，因为它依赖于jruby中不可用的叉子。
