Mini_racer 0.2.0 causing bundler to fail

support
1

I am upgrading Discourse to 2.1.6 from 1.9.6, and I cannot get through bundle install. I am using Docker (ubuntu 16.04) as the base image to build discourse. Ruby version 2.3.0. When I get to bundle install, I get the following compilation error. Urgent Help! Not sure what else I’m missing…

==============================

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

Gem files will remain installed in
/usr/local/rbenv/versions/2.3.0/lib/ruby/gems/2.3.0/gems/mini_racer-0.2.0 for

An error occurred while installing mini_racer (0.2.0), and Bundler cannot
continue.
Make sure that `gem install mini_racer -v '0.2.0' --source
'https://rubygems.org/'` succeeds before bundling.

In Gemfile:
  mini_racer

Looking at the gems getting installed, I do see this (which I believe is what mini_racer depends on):

Fetching libv8 6.7.288.46.1 (x86_64-linux)
