I’m still fascinated with the Jekyll approach to website management, and am working on converting one of my blogs (not Unix Tutorial just yet!) to Jekyll website. This short post shows how to install Jekyll on a Linux Mint system.
Install Ruby and Bundler
First things first: you need to install Ruby:
greys@xps:~/proj$ sudo apt install ruby
Reading package lists... Done
Building dependency tree
Reading state information... Done
The following package was automatically installed and is no longer required:
libssh-4
Use 'sudo apt autoremove' to remove it.
The following additional packages will be installed:
libruby2.5 rake ruby-test-unit ruby2.5
Suggested packages:
ri ruby-dev
Recommended packages:
fonts-lato libjs-jquery
The following NEW packages will be installed:
libruby2.5 rake ruby ruby-test-unit ruby2.5

… and now use the gem command to install bundler gem:
greys@xps:~/proj$ sudo gem install bundler

Install the Jekyll gem
Excellent, we’re really close to getting this working.
Only small problem: when installing the jekyll gem, there’s an error:
greys@xps:~/proj$ sudo gem install jekyll
Building native extensions. This could take a while...
ERROR: Error installing jekyll:

I first thought I did something wrong or that I have an old version of Ruby (2.5.0 as you can see). But now, it seems the minimal required version for Jekyll is Ruby 2.1.0 so it should all work.
The hint is in the error message:
mkmf.rb can't find header files for ruby at /usr/lib/ruby/include/ruby.h
This include file is indeed missing, because previously we simply installed Ruby binaries, but not the development packages.
Once we install ruby-dev package:
greys@xps:~/proj$ sudo apt install ruby-dev

Ruby Sass is deprecated and will be unmaintained as of 26 March 2019.
- If you use Sass as a command-line tool, we recommend using Dart Sass, the new
primary implementation: https://sass-lang.com/install
- If you use Sass as a plug-in for a Ruby web framework, we recommend using the
sassc gem: https://github.com/sass/sassc-ruby#readme

Great stuff! Now we can serve my project and browse to the Jekyll page (I skip the jekyll steps for starting new website because they’re described in my Jekyll website with GitHub Pages article):
