【问题描述】：
我使用了 ruby 1.9.2 和 rails 3.0.3。我正在尝试安装 rmagick gem，但是当我运行 bundle install 时出现错误告诉我：
Installing rmagick (2.12.1) with native extensions c:/Ruby192/lib/ruby/site_ruby

我从http://rubyinstaller.org/downloads/ 安装了带有开发工具包和最新版 ImageMagick 的 ruby。我尝试设置 rmagick 配置（lib 和包含目录），但我仍然得到同样的错误
有什么帮助吗？有什么想法可以解决这个问题？
