This post was initially published on November 18, 2015. Since then I have moved to Ghost as my blogging platform.
Out of the box, I did not have a working Ruby environment for Jekyll, so I needed to set one up quickly.
Here's a quick Jekyll setup for my own future reference (when OS X 10.12 is out).
cd Projects/takashiyoshida.github.io rbenv local 2.2.3 gem install bundler rbenv rehash bundle install rbenv rehash
Once done with the setup, you can run Jekyll like this.
jekyll build jekyll serve --drafts
