从代码使用时Laravel Artisan命令不起作用

Question

我创建了一个laravel命令，如下：

class CreateFirstUserCommand extends Command
{
    protected $signature = 'firsttenant:create {name}';
    protected $description = 'Creates first user in database with name';

    public function handle()
    {
        $name       = $this->argument('name');
        $website    = new Website();
        app(WebsiteRepository::class)->create($website);

        $hostname       = new Hostname;
        $hostname->fqdn = $name.'.site.me';
        $hostname       = app(HostnameRepository::class)->create($hostname);
        app(HostnameRepository::class)->attach($hostname, $website);

        $tenancy = app(Environment::class);
        $tenancy->hostname($hostname);

        // resolves $hostname as currently active hostname
        $tenancy->hostname(); 

        // switches the tenant and reconfigures the app
        $tenancy->tenant($website); 

        // resolves $website
        $tenancy->website(); 

        // resolves $website
        $tenancy->tenant(); 
        $tenancy->identifyHostname();
        sleep(10);

        $role       = Role::create(['name' => 'tenant']);
        $permission = Permission::create(['name' => 'all']);

        $user= new User();
        $user->name = $name;
        $user->email = 'admin@'.$name.'.site.me';
        $user->password = Hash::make('12344321');
        $user->assignRole('tenant');
        $user->save();
    }
}

我从控制台调用此命令的方式为：

  

php artisan firsttenant：创建Alpha

并按预期工作正常，但是当我从代码中调用时如下：

  

Artisan :: call（'firsttenant：create'，['name'=> $ name]）;

它不执行任何操作。
