If you'd like, you can continue manually registering your commands. But L5.5 gives you the option to lazy load them. If you are upgrading from an older version add this method to your Kernel:

如果您愿意，可以继续手动注册您的命令。但是 L5.5 为您提供了延迟加载它们的选项。如果您是从旧版本升级，请将此方法添加到您的内核：

/**
 * Register the commands for the application.

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

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

By changing signaturein your command class to your commandName. change

通过将您的命令类中的签名更改为您的commandName。改变

protected $signature = 'command:name';

TO

到

protected $signature = 'NeighborhoodCommand';

Now try to run

现在尝试运行

$ php artisan NeighborhoodCommand

It works for me.

这个对我有用。
