Upgrading to JRuby | Neo4J | rvm on Ubuntu

While upgrading the Wikibrains server I encountered a few snags, I had to bypass these issues by following these steps:

Purging the RVM/Ruby installations: (source)

sudo apt-get --purge remove ruby-rvm
sudo rm -rf /usr/share/ruby-rvm /etc/rvmrc /etc/profile.d/rvm.sh

open new terminal and validate environment is clean from old RVM settings (should be no output):

env | grep rvm

if there was output, try to open new terminal, if it does not help then restart your computer.

install RVM:

\curl -L https://get.rvm.io | 
  bash -s stable --ruby --autolibs=enable --auto-dotfiles

Then Run:

source /usr/local/rvm/scripts/rvm

Now proceed to installing rails:

gem install rails --version '= 0.3.8'

gem install bundler




creating the application with neo4j.rb:

rails _3.2.8_ new myapp -m http://andreasronge.github.com/neo4j/rails.rb -O

note: at the time of this post, there is a conflict between Neo4j.rb and rails 4 dependencies.
