Today the Laravel team released a new major version of “laravel/installer” that includes support for quickly starting Jetstream projects. With this new version when you run “laravel new project-name” you’ll get Jetstream options. For example:
laravel new foo --jet --dev
Then it’ll ask you which Jetstream you prefer:
Which Jetstream stack do you prefer?  Livewire  inertia > livewire Will your application use teams? (yes/no) [no]: ...
If you already have the installer installed, to get the version all you should need to run is
composer global update but that didn’t work for me. Instead, I had to uninstall then reinstall:
composer global remove laravel/installer composer global require laravel/installer
