配个rforum头都大了。解决办法

配个rforum头都大了。。
E:/Ruby/lib/ruby/gems/1.8/gems/actionpack-2.3.5/lib/action_controller/routing/builder.rb:94:in `assign_route_options': Regexp anchor characters are not allowed in routing requirements: /^[0-9]+$/ (ArgumentError)

builder.rb文件里
if requirement.source =~ %r{\A(\\A|\^)|(\\Z|\\z|\$)\Z}
  raise ArgumentError, "Regexp anchor characters are not allowed in routing requirements: #{requirement.inspect}"
  end


请各位达达指教。。。配个rforum都快疯了 建论坛还有什么开源的源码吗
