非常直接：
C:\Ruby192>gem install apriori
Temporarily enhancing PATH to include DevKit...
Building native extensions. This could take a while...

我是红宝石和宝石的新手，但如果我说得对，抱怨的就是RakeFile：
require 'config/requirements'
require 'config/hoe' # setup Hoe + all gem configuration
但文件真的存在：
c:\Ruby192>ls -l C:/Ruby192/lib/ruby/gems/1.9.1/gems/apriori-0.2.2/config

Windows路径可能有问题吗？出于某种原因阻止rake查找文件？
