Few issues due to Ruby old version

[alsilva86]

Hi! I want to test your solution, I have been trying to follow the instructions on your website to install.
Here is where I got stucked.
I followed instructions to install Ruby (2.1.0) unsupported.

Changed in 20140313044626_create_projects.rb
from ActiveRecord::Migration
to
class CreateProjects < ActiveRecord::ConnectionAdapters::Mysql2Adapter
I do successfuly the rake::create

When I try: rake::migrate

ubuntu@ip-172-31-24-23:/fluxday-master/config$ rake db:migrate --trace
(in /home/ubuntu/fluxday-master)
** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
** Invoke db:load_config (first_time)
** Execute db:load_config
** Execute db:migrate
rake aborted!
