推荐答案

nokogiri 安装教程 提供解决方案:

# bash
brew unlink gcc
gem uninstall nokogiri
xcode-select --install
gem install nokogiri

如果您还没有 Xcode 6.1，您可以从 apple developer 下载站点安装它(其他工具部分)，如 此博客中所述发帖.

If you don't have Xcode 6.1, yet, you may install it from the apple developer download site (section additional tools), as described in this blog post.
