PHP Artisan Tinker crashing from any command

问题:

I haven't had this problem before, but my php artisan tinker crashes from issuing any command - and leaves no logs whatsoever on what is causing the crash.

project4 $ php artisan tinker
Psy Shell v0.9.9 (PHP 7.3.0 — cli) by Justin Hileman
>>> use \App\Jobs\testJob;
project4 $

or even the simplest command:

project4 $ php artisan tinker
Psy Shell v0.9.9 (PHP 7.3.0 — cli) by Justin Hileman
>>> print("Hello World!");
project4 $

I almost wonder if it isn't connecting to PHP correctly, but I can't find any logs anywhere. Laravel has no trace of the commands. I ran brew update, but no difference. For the record, all of my projects are affected. I can't tinker on any of my projects. Help!

I did recently upgrade to PHP 7.3.0, which is working fine in every other area. Hmm...

If you are using PHP 7.3 installed by homebrew on Mojave, try creating a config file at ~/.config/psysh/config.php if not already there:

<?php
return [
  'usePcntl' => false,
];
