bundle install fails on the nokogiri gem

[Cory S]

Hello,

I just created a Rails project on Ubuntu 16.04 and went to 'bundle install' but it failed on nokogiri. Nokogiri is not in my Gemfile, so I suppose it is a dependency. The logs they ask me to check out on failure don't seem to exist.

I tried the instructions here, but with no luck.

Here's the message I got from 'bundle install':

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

To see why this extension failed to compile, please check the mkmf.log which can be found here:

That sure looks like a show-stopper but on a fresh vagrant box with
16.04.1 (ubuntu/xenial32) I just did the following:

> sudo apt-get install ruby

> sudo apt-get install zlib1g-dev
> sudo gem install nokogiri

:: and done. So how was your system built?

This worked! Thank you! I'm on native Ubuntu, not a virtual machine.
