Getting error when registering device

I am following the directions on the site, I installed the CLI on my mac, did matrix register to create new account, but I am getting the following error when I try to run matrix register device:
matrix register device
/usr/local/lib/node_modules/matrix-cli/bin/matrix-validate.js:23
var token = Matrix.config.user.token;
^

TypeError: Cannot read property ‘token’ of undefined

This is what I did:

Thanks, I literally just installed the client. For good measure, I uninstalled, reinstalled same error.
Thanks for the pointer though, I’ll move this to git
