I prefer to run ruby stuff under Linux rather than Windows. I run Windows 10, so will be using the Ubuntu 16.04 image for the Windows Subsystem for Linux. Though these steps should work in a full installation of Ubuntu as well.
Install Ruby
sudo apt install ruby ruby-dev ruby-bundler
Install dev dependencies
sudo apt install gcc make build-essentials
Install Jekyll
sudo gem install jekyll
Install bundler dependencies
bundler install
I have the best luck running jekyll with bundler exec
bundler exec jekyll build
bundler exec jekyll serve
Happy blogging!
