error when executing php artisan migrate seed in console - laravel

Question

I write php artisan migrate:fresh --seed in the console of the root folder of a project, when I run this command, it takes near to 1 minute then it returns \
In PackageServiceProvider.php line 14:
syntax error, unexpected 'Package' (T_STRING), expecting function (T_FUNCTION) or const (T_CONST)
PackageServiceProvider.php:
namespace Spatie\LaravelPackageTools;
use Carbon\Carbon;
use Illuminate\Support\Facades\View;
use Illuminate\Support\ServiceProvider;
use Illuminate\Support\Str;
use ReflectionClass;
use Spatie\LaravelPackageTools\Exceptions\InvalidPackage;
abstract class PackageServiceProvider extends ServiceProvider
{
protected Package $package; /* line 14 */
abstract public function configurePackage(Package $package): void;
public function register()
{
$this->registeringPackage();
$this->package = new Package();
$this->package->setBasePath($this->getPackageBaseDir());
$this->configurePackage($this->package);
if (empty($this->package->name)) {
throw InvalidPackage::nameIsRequired();
}
foreach($this->package->configFileNames as $configFileName) {
$this->mergeConfigFrom($this->package->basePath("/../config/{$configFileName}.php"), $configFileName);
}
$this->packageRegistered();
return $this;
}
.
.
.
.
}
the project's author's PHP version: 7.4.19
my PHP version: 7.3.27
I'm noob in laravel, so if I have to show up with more info about the issue tell me. \
edit
after updating the PHP version to 7.4.21
I wrote the command and it returned
C:\xampp\htdocs\Business-Manager>php artisan migrate:fresh --seed

Answer 1

Your problem is that protected Package $package; is PHP 7.4, it should be like protected $package;.
As you can see in the source code, it required php ^7.4 or ^8.0, so you have to change your PHP to either of those.
This is another place to see the composer package you are downloading, to see more info about it...

Answer 2

import suitable class in the top.
use Facade\Ignition\Support\Packagist\Package;
