I am getting a curl error

I'm enrolled in the beginner WordPress course, and I'm having difficulty setting up the virtual box/vagrant test environment. I believe the page you have for setting it up may be outdated

For reference, I'm running on a mid-2014 MacBook pro.

When I use the recommended command, I get this error:

'curl' is not recognized as an internal or external command,
operable program or batch file.
