RMagick安装无法构建本机扩展
在山狮我试图安装RMagick。 我在GitHub上发现了一个问题，解决方案应该是命令gem pristine rmagick 。 但是当我运行它时，我得到：
ERROR: While executing gem ... (Gem::Exception) Failed to find gems ["rmagick"] >= 0
当我运行gem install rmagick ，我收到了这个巨大的错误：
Building native extensions. This could take a while...

ImageMagick的版本是6.7.7-6。
你能帮帮我，如何摆脱这个错误以及如何最终在Mountain Lion上安装RMagick？
你是否在安装gem之前使用brew来安装’imagemagick’？
这有助于：
brew update brew remove imagemagick brew install imagemagick
其他如果以前仍未解决您的问题：
brew install freetype
要么
brew unlink freetype && brew link freetype
或者安装XQuartz 。
或者在rmagick GitHub页面上查看此评论 。
要么
ln -s /opt/X11/lib/libfreetype.6.dylib /usr/local/lib/libfreetype.6.dylib
