我目前使用的是Redcarpet 3.1.2，使用OS X El Capitan 10.11.2
我正在尝试运行'bundle exec jekyll serve'，但似乎我必须运行一个bundle install。这是安装错误输出的地方

An error occurred while installing redcarpet (3.3.3), and Bundler cannot continue.
Make sure that `gem install redcarpet -v '3.3.3'` succeeds before bundling.
我怀疑这是上次OS X更新（2015年12月15日）产生的问题。
