Ruby on rails 尝试运行脚本/控制台时获取“无效选项：-Ku（OptionParser:：InvalidoOption）”

尝试在生产设备上运行脚本/控制台时，我遇到以下错误：

/data/site/shared/bundle/ruby/1.9.1/gems/rails-2.3.11/lib/commands/console.rb:11:in `block in <top (required)>': invalid option: -Ku (OptionParser::InvalidOption)
    from /data/site/shared/bundle/ruby/1.9.1/gems/rails-2.3.11/lib/commands/console.rb:6:in `new'
    from /data/site/shared/bundle/ruby/1.9.1/gems/rails-2.3.11/lib/commands/console.rb:6:in `<top (required)>'
    from script/console:3:in `require'
    from script/console:3:in `<main>'

你知道为什么会这样吗

谢谢。

更新到Ruby 1.9.2-p290解决了这个问题

/data/site/shared/bundle/ruby/1.9.1/gems/delayed_job-2.0.7/lib/delayed/command.rb:51:in `initialize': invalid option: -Ku (OptionParser::InvalidOption)
    from script/delayed_job:5:in `new'
    from script/delayed_job:5:in `<main>'
