必须安装 Yosemite 来解决 Wi-Fi 问题，但现在安装rmagick失败。我已经尝试了 StackOverflow 和 Github 上每篇文章的所有内容，但安装仍然失败。

我正在使用通过ruby 2.1.1p76 (2014-02-24 revision 45161) [x86_64-darwin13.0]安装rbenv

$ brew remove imagemagick
$ brew install imagemagick --disable-openmp
$ cd /usr/local/Cellar/imagemagick/6.8.9-1/lib
$ ln -s libMagick++-6.Q16.3.dylib libMagick++.dylib
$ ln -s libMagickCore-6.Q16.dylib libMagickCore.dylib
$ ln -s libMagickWand-6.Q16.dylib libMagickWand.dylib
$ sudo ln -s /usr/bin/gcc /usr/bin/gcc-4.2
$ C_INCLUDE_PATH=/usr/local/Cellar/imagemagick/6.8.9-1/include/ImageMagick-6/ gem install rmagick

但失败了：

任何建议都会有帮助。谢谢。

PS运行后令我惊恐的是，gem cleanup我意识到无论我做什么，我都无法安装nokogiri......

我只是在 OSX 10.10 上遇到了同样的问题（并且经历了你经历的大部分步骤）。如果您使用CC=clang前缀安装了 ruby​​，请导航到/usr/bin并运行：

sudo unlink gcc-4.2
sudo mv gcc gcc-foo
sudo ln -s clang gcc

如果您仍然遇到问题，我可能会尝试sudo ln -s clang gcc-4.2

根据Github 上的建议，我删除gcc 4.2并重建了 Ruby。这解决了rmagick和的所有问题nokogiri。
