When I run composer update, I get the following error:
Loading composer repositories with package information Updating dependencies (including require-dev) Nothing to install or update Generating autoload files Illuminate\Foundation\ComposerScripts::postUpdate php artisan optimize [Symfony\Component\Debug\Exception\FatalErrorException] Class 'Laravel\Cashier\CashierServiceProvider' not found Script php artisan optimize handling the post-update-cmd event returned with err or code 255
I put this code on the app.php file
Laravel\Cashier\CashierServiceProvider::class,
and in the composer.json I also put this
"laravel/cashier": "~6.0"
like in the laravel doc
Remove the
Laravel\Cashier\CashierServiceProvider::class,
from app.php. It needs to be added after installing the package.
Also, instead of composer update, try composer require without changing the composer.json file.
composer require laravel/cashier
