Laravel update via composer

The problem is when Composer downloads the updates.

Laravel includes in the Composer file some internal commands for Cache cleanup, Autoload optimization, etc.:

"scripts": {
    "post-install-cmd": [
        "php artisan clear-compiled",
        "php artisan optimize"
    ],
    "post-update-cmd": [
        "php artisan clear-compiled",
        "php artisan optimize"
    ],
    "post-create-project-cmd": [
        "php -r \"copy('.env.example', '.env');\"",
        "php artisan key:generate"
    ]
},

In the response you posted, you were missing an important step: run composer update after changing the composer.json file. Since Composer executes a Laravel command and then you entered the Service Provider Collective\Html\HtmlServiceProvider , it did not exist at the time and caused the error.

You can fix it in two ways:

In this specific case the error occurred in the /var/www/laravel/laravel/vendor/laravel/framework/src/Illuminate/Foundation/ProviderRepository.php file after I ran the composer update, the error was at line 150, in case it was a syntax error, thanks for trying to help.
