系统 ruby​​ 安装似乎搞砸了。尝试删除有问题的 /Library/Ruby/Site/2.0.0/rubygems.rb(并且可能是更多的封闭文件夹)

Ruby 在 /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0 中有其捆绑的 ruby​​gems，因此它应该与这些一起工作。

一旦 ruby​​ 可用 - 如果需要，您可以尝试通过 sudo gem update --system 再次升级 ruby​​gems，但我建议设置一个 ruby​​ 版本管理器，如 rvm ( rvm.io) 并让系统 ruby​​ 仅在紧急情况下存在并支持 brew。
