Installing rebenv

Mint comes with a ruby package installed. It is installed as the root user and is not the latest version. We want the flexibility to install the latest version, to be able to easily upgrade and not have the hassles of installing gems as root.

To do this we need to use Ruby environment manager. This allows everyone on your team to be on the same version of Ruby, regardless of OS. This can be locked in with a .ruby-version in the root directory of your project.

I recommend rbenv to do this.

Dependencies

The software we're installing needs a few dependencies installed in order to work.
