Ruby Gem Nokogiri Not Installing on Rails 3.2.11 - ruby

Question

I am trying to run a Rails app through Docker that is using Rails 3.2.11. The gem nokogiri is not being installed when I run bundle install.
I have this in my Gemfile:
gem 'nokogiri', '~> 1.6.8.rc2'
And this in my LOCK file:
nokogiri (1.6.8.rc2)
mini_portile2 (~> 2.1.0)
When I try running bundle install through docker, I get the following error messages:
************************************************************************

An error occurred while installing nokogiri (1.6.8.rc2), and Bundler cannot continue.
Make sure that `gem install nokogiri -v '1.6.8.rc2'` succeeds before bundling.
In Gemfile:
fog was resolved to 1.23.0, which depends on
nokogiri
I've tried modifying the Gem File a few times but it keeps resulting in Nokogiri not being installed properly.
Any help is greatly appreciated!

Make sure libxml2 is installed on your machine. Is it available to install with brew install or apt-get install depending on your OS.
Update: also if you're trying to run your app inside of docker container add libxml2 too and install nokogiri with RUN gem install nokogiri -v '1.6.8.1' in your Dockerfile
