【问题描述】：
我想重新安装我的 ruby on rails 环境，但是失败了。
我在 Mac OS X 10.9.2 上工作，使用 Ruby 2.1.2，Apple LLVM 版本 5.1 (clang-503.0.40 )
我想跑步：
gem install eventmachine -v '1.0.3'
但我明白了：
Building native extensions. This could take a while...
ERROR: Error installing eventmachine:

Gem files will remain installed in /Users/nm/.rbenv/versions/2.1.2/lib/ruby/gems/2.1.0/gems/eventmachine-1.0.3 for inspection.

当我安装版本 1.0.1 或 1.0.2 时，我会遇到一些类似的错误。
谁能告诉我为什么？谢谢。
