An error occurred while installing nokogiri (1.8.4), and Bundler cannot
continue.
Make sure that `gem install nokogiri -v '1.8.4' --source
'https://rubygems.org/'` succeeds before bundling.
In Gemfile:
github-pages was resolved to 188, which depends on
jekyll-mentions was resolved to 1.4.0, which depends on
html-pipeline was resolved to 2.8.3, which depends on
nokogiri
All we need is to install “nokogiri-1.8.4” extenstions first, so we just install it at shell:
gem install nokogiri -v '1.8.4' --source 'https://rubygems.org/'

As log discription, we lost zlib (
zlib1g-dev), ok, let’s get is install:
sudo apt-get install zlib1g-dev
That’s all right, we could continue install “nokogirl-1.8.4” and next run “bundle install”
