我一直试图将我们的api从Laravel迁移到Lumen但是当我尝试运行一个简单的工匠命令时，我得到了这个错误：

这就是我们app.php的样子

我知道不是Laravel的所有功能都存在于Lumen中，但我在这里缺少什么？
<?php
namespace Websight\GcsProvider;
use ErrorException;
use Google_Auth_AssertionCredentials;
use Google_Client;
use Google_Service_Storage;
use Illuminate\Support\ServiceProvider;
use League\Flysystem\Filesystem;
use Illuminate\Support\Facades\Storage;
use Superbalist\Flysystem\GoogleStorage\GoogleStorageAdapter;
/**
* Class CloudStorageServiceProvider
* Configures Google Cloud Storage Access for flysystem
*
* @package Websight\GcsProvider
*/
class CloudStorageServiceProvider extends ServiceProvider
{
/**
* Bootstrap the application services.
*
* @return void
*/
public function boot()
{
Storage::extend('gcs', function ($app, $config) {
$credentials = new Google_Auth_AssertionCredentials(
$config['service_account'],
[
Google_Service_Storage::DEVSTORAGE_FULL_CONTROL
],
file_get_contents($config['service_account_certificate']),
$config['service_account_certificate_password']
);
$client = new Google_Client();
$client->setAssertionCredentials($credentials);
$service = new Google_Service_Storage($client);
$adapter = new GoogleStorageAdapter($service, $config['bucket']);
return new Filesystem($adapter);
});
}
/**
* Register the application services.
*
* @return void
*/
public function register()
{
// Not needed
}
}
