我最终开始使用整个rbenv，ruby和rails安装。

brew update

brew uninstall --force ruby

brew uninstall --force openssl

brew install openssl

brew link openssl --force

brew uninstall --force ruby-build

然后我按照本指南进行操作： https://gorails.com/setup/osx/10.11-el-capitan

安装rails时出现libxml2错误：

libxml2 is missing.  Please locate mkmf.log to investigate how it is failing.

我通过运行

修复了这个问题

$  gem install nokogiri -- --use-system-libraries  [--with-xml2-config=/path/to/xml2-config]  [--with-xslt-config=/path/to/xslt-config]
