Usually you see this error when Craft CMS is not installed yet or the credentials to the database are not correct. You can run the Installer from the command line via ./craft install or by going to http://yardstick.dev.com/admin.

On another note, I can highly recommend to run local Craft CMS setups with ddev. It will make a lot of things easier for you.
