On macOS High Sierra (and perhaps earlier), cron is disabled in some configurations. There is, however, still a LaunchDaemon for it.

Check to see if cron is enabled:

sudo launchctl list | grep cron
You should see com.vix.cron.plist if cron is running. If cron is not running, you should do:

sudo launchctl load -w /System/Library/LaunchDaemons/com.vix.cron.plist
That will start cron, and the -w switch will make sure it starts after reboots as well.

Open terminal
> ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
Say yes to X-Code (have fast connection for download)
> brew install rbenv ruby-build

Add rbenv to bash so that it loads every time you open a terminal
> echo 'if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi' >> ~/.bash_profile
> source ~/.bash_profile
