I've git a Docker container based on phusion/baseimage and inside this container I compiled ruby 2.1.2 myself.
I try to install the gem livingstyleguide and during this process redcarpet 3.0.0 will be installed. This always fails and I don't know why.
This is the output:
ERROR: Error installing livingstyleguide:
ERROR: Failed to build gem native extension.
