• composer require richdynamix/arc:2.0
• php artisan arc:install Expected: successful copy and cleaning after Result: the requested PHP extension pcntl is missing from your system.

Your requirements could not be resolved to an installable set of packages.

Problem 1

• laravel/horizon v2.2.2 requires ext-pcntl * -> the requested PHP extension pcntl is missing from your system.
• laravel/horizon v2.2.2 requires ext-pcntl * -> the requested PHP extension pcntl is missing from your system.
• laravel/horizon v2.2.2 requires ext-pcntl * -> the requested PHP extension pcntl is missing from your system.
• Installation request for laravel/horizon (locked at v2.2.2, required as ^2.2) -> satisfiable by laravel/horizon[v2.2.2].

Updated in Release 2.1.0.

I originally added this to the project composer install for use in the Docker image but not when cleaning up the arc install.
