ruby-on-rails – 如何在os x 10.8.3上安装rmagic 2.12.2

我成功安装了最新版本的rmagic 2.13.2,但很明显,宝石需要的旧版本有一些路径问题,我安装的imagemagick女巫是版本6.8.0-10

我已经阅读了很多帖子都说要设置不同的环境路径,使用brew和bla bla bla重新安装imagemagic.主要问题是rmagic版本,它依赖于imagemagick的位置和版本

我从gem安装中获得的当前错误如下.

Can't install RMagick 2.12.2. Can't find the ImageMagick library or one of the dependent libraries. Check the mkmf.log file for more detailed information.

necessary libraries and/or headers.  Check the mkmf.log file for more
