I get this error in the console while running app:build

Undefined constant "SIGINT"

I just came across this too. You need to have PHP's pcntl extension installed for this to work. (Note that this extension is not available on Windows.)

I think this can be fixed pretty easily the same way spatie/laravel-backup#1311 does it, I'm going to see if I can submit a PR for it.
