在Mountain Lion上我正在尝试安装RMagick。我找到了issue on GitHub，解决方案应该是命令gem pristine rmagick。但是当我运行它时，我得到了：
ERROR: While executing gem ... (Gem::Exception)
Failed to find gems ["rmagick"] >= 0
当我运行gem install rmagick时，我收到了这个巨大的错误：
Building native extensions. This could take a while...
ERROR: Error installing rmagick:

ImageMagick的版本是6.7.7-6。
请帮助我，如何摆脱这个错误以及如何最终在Mountain Lion上安装RMagick？
答案 0 :(得分：0)
您是否在安装gem之前使用brew来安装'imagemagick'？
这可能有所帮助：
brew update
brew remove imagemagick
brew install imagemagick
其他如果前一个仍未解决您的问题：
brew install freetype
或者
brew unlink freetype && brew link freetype
或安装XQuartz。
或者查看this comment on the rmagick GitHub page。
或
ln -s /opt/X11/lib/libfreetype.6.dylib /usr/local/lib/libfreetype.6.dylib
