我有一个需要做一些后台工作的网络应用程序。我有一个clock.rb文件，其中包含：

require 'clockwork'
include Clockwork

require './config/boot'
require './config/environment'

every(5.seconds, 'ticking.get') { Resque.enqueue(TickingJob) }
[...rest of the code irrelevant...]

当我尝试使用 启动文件时clockwork app/clock.rb，出现以下错误：

/usr/local/rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/yaml.rb:56:in `<top (required)>':
It seems your ruby installation is missing psych (for YAML output).
To eliminate this warning, please install libyaml and reinstall your ruby.

关于“psych”的第一个错误似乎无关紧要（我每次都得到它，并且我确实重新安装了libyaml）。至于第二个，我不知道。模块的代码activesupport不好吗？

您需要将include Clockwork行移至以下require行：

require 'clockwork'    
require './config/boot'
require './config/environment'

include Clockwork

every(5.seconds, 'ticking.get') { Resque.enqueue(TickingJob) }
