我目前有 Redcarpet 3.1.2，使用 OS X El Capitan 10.11.2
我正在尝试运行“bundle exec jekyll serve”，但似乎我必须运行捆绑安装。这是安装错误的地方

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）引起的问题。
