我正在本地主机上用Laravel 7.28构建一个项目。我需要每小时更新一个PDF。开始时我创建了一个命令：

<?php

namespace App\Console\Commands;

use App\Event;
use Illuminate\Console\Command;

class PDF extends Command
{
    /**
     * The name and signature of the console command.
     *
     * @var string
     */
    protected $signature = 'pdf:update';

    /**
     * The console command description.
     *
     * @var string
     */
    protected $description = 'All Country PDFs updated';

    /**
     * Create a new command instance.
     *
     * @return void
     */
    public function __construct()
    {
        parent::__construct();
    }

    /**
     * Execute the console command.
     *
     * @return int
     */
    public function handle()
    {

        $event = new Event();
        $event->user_id = 1;
        $event->save();

        echo 'done';
    }
}

它只是在事件表中插入一条记录，工作正常。然后我编辑了App\Console目录下的Kernel.php。

<?php

namespace App\Console;

use Illuminate\Console\Scheduling\Schedule;
use Illuminate\Foundation\Console\Kernel as ConsoleKernel;

class Kernel extends ConsoleKernel
{
    /**
     * The Artisan commands provided by your application.
     *
     * @var array
     */
    protected $commands = [
        Commands\PDF::class,
    ];

    /**
     * Define the application's command schedule.
     *
     * @param \Illuminate\Console\Scheduling\Schedule $schedule
     * @return void
     */
    protected function schedule(Schedule $schedule)
    {
        $schedule->command('pdf:update')->everyMinute();
    }

    /**
     * Register the commands for the application.
     *
     * @return void
     */
    protected function commands()
    {
        $this->load(__DIR__ . '/Commands');

        require base_path('routes/console.php');
    }
}

最后，我运行php artisan schedule:run。我希望该命令每分钟运行一次，但它只运行一次。这是localhost上的问题还是我做错了什么？
