PHP Artisan Tinker crashing all the time on MacOS Mojave

txt

Problem: PHP Artisan Tinker crashes from issuing any command and leaves no logs. 

Solution: 

According to developer's forum: https://github.com/bobthecow/psysh/issues/540#issuecomment-446480753 it is necessary to edit
the following file: 

~/.config/psysh/config.php in case the file do not exist just create a new one vim ~/.config/psysh/config.php 

Add the following content: 

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

:wq! 

Done!
