Lumen 5.3:/var/www/project/vendor/illume/container/container.php:749中的“类文件系统不存在”

我一直在尝试将我们的api从Laravel迁移到Lumen，但在尝试运行简单的artisan命令时，出现以下错误：

这就是我们的app.php的样子

我知道不是所有的功能，从拉威尔是目前在流明，但有什么我在这里错过了

<?php

use Google_Auth_AssertionCredentials;
use Google_Client;
use Google_Service_Storage;

use Superbalist\Flysystem\GoogleStorage\GoogleStorageAdapter;

    /**

     * 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
                    ],

在bootstrap/app.php中的容器绑定下添加以下内容

Websight\GcsProvider\CloudStorageServiceProvider的启动方法中有什么东西正在使用文件系统，它无法解决。@我向服务提供程序发布了一个问题吗？我收到一个错误php artisan list php致命错误：达到最大函数嵌套级别“256”，正在中止！在第580行的/var/www/folder/vendor/laravel/lumen framework/src/Application.php中，php堆栈跟踪：PHP1。{main}/var/www/folder/artisan:0这似乎是Laravel 5.3.0的问题，在5.3.1中得到了修复。在Lumen 5.5中，我添加了上述代码，并在app/config/filesystems.php中添加了一个从这里复制的配置文件。在Lumen 5.6中，我还必须在composer.json:league/flysystem:^1.0.8中添加flysystem依赖性

$app->singleton('filesystem', function ($app) {
    return $app->loadComponent('filesystems', 'Illuminate\Filesystem\FilesystemServiceProvider', 'filesystem');
});
