Ruby and rbenv

  1. Install rbenv (via "basic github checkout")
  2. Install ruby-build as an rbenv plugin.
  3. At this point you made need to run sudo apt-get install -y libssl-dev libreadline-dev zlib1g-dev before proceeding
  4. rbenv install -l lists available versions of Ruby. Pick one to install.
  5. Set that version to global.

You can update the Ruby versions available to rbenv by running rbenv_upgrade (found in bashrc).

function rbenv_upgrade {
  cd ~/.rbenv && git pull
  cd ~/.rbenv/plugins/ruby-build && git pull
  cd ~
