Vagrant Box Setup and Ruby

[Tropicalrambler]

I had difficulty on macOS using the commands given, perhaps because gems was not installed so I downloaded this file
https://rubygems.org/pages/download

then opened in terminal and switched directories there:

sudo ruby setup.rb

And then I ran:

gem install vagrant-vbguest
gem install vagrant-notify-forwarder

This was useful on a slow network connection!

That's weird. Installing vagrant and then using vagrant to install the plugins should work. Did you not do that?
