Ruby(2.2.2) Rails(4.2.3) Installation Ubuntu(14.04)

# These are the suggested installation instructions for Ubuntu for class. There is
# lengthy compilation step in the middle of these procedures, so please plan on
# 30min break to complete the "rbenv install" command.

# The instructions start with a visit to the official Rails site (http://rubyonrails.org).
# The download page (http://rubyonrails.org/download/)
# recommends that we install the rbenv installation manager to manage our ruby installation
# and supplies a link to git://github.com/sstephenson/rbenv.git
# There are more words about the rbenv, ruby, and rails installation on the Ubuntu page
# https://www.digitalocean.com/community/tutorials/how-to-install-ruby-on-rails-with-rbenv-on-ubuntu-14-04
# we will mix into the instructions.

#exit if we encounter an error
set -e

#before we start -- make sure your packages are up-to-date and has some necessary tools

#update installed packages before adding new ones
sudo apt-get update -y

# install Git required to clone source repositories and work with ourselves
sudo apt-get install -y git gitk git-gui

# install C-compiler and libraries required by rbenv to build ruby binaries for your platform
sudo apt-get install -y gcc build-essential libpq-dev libssl-dev libreadline-dev libsqlite3-dev zlib1g-dev

# Now follow the rbenv instructtions on the Github site
# https://github.com/sstephenson/rbenv
#clone the rbenv git repo into ~/.rbenv
git clone git://github.com/sstephenson/rbenv.git .rbenv

echo 'eval "$(rbenv init -)"' >> ~/.bashrc

#add the contents of the modified .bashrc to your current shell

#add the install command to rbenv

# install a Ruby version (could be others)
rbenv install -v 2.2.2
# set the global version of Ruby to use
rbenv global 2.2.2
ruby -v

#set the default to not have gems generate local documentation (and eat space and time)
echo "gem: --no-document" > ~/.gemrc
gem install bundler

#this step will take a ~5min to complete (as it warns)
