Laravel 错误 “ReflectionException” - “类应用\Http\Kernel 不存在”

我试图用一个我在学校一年前开发的laravel项目上线，我遇到了一些问题。在我的托管服务的服务器上上传整个项目后，我在浏览器以及SSH shell上收到了这些错误。

致命错误：未捕获的异常“ReflectionException”，消息“类 App\Http\Kernel 不存在”在 /home/clients/ffa41f94063541f86a0fe6602a73caa1/myforms/vendor/laravel/framework/src/Illuminate/Container/Container.php：779 Stack trace： #0 /home/clients/ffa41f94063541f86a0fe6602a73caa1/myforms/vendor/laravel/framework/src/Illuminate/Container/Container/Container.php（779）： ReflectionClass->__construct（'App\Http\Kernel'） #1 /home/clients/ffa41f94063541f86a0fe6602a73caa1/myforms/vendor/laravel/framework/src/Illuminate/Container/Container.php（659）： Illuminate\Container\Container->build（'App\Http\Kernel'， Array） #2 /home/clients/ffa41f94063541f86a0fe6602a73caa1/myforms/vendor/laravel/framework/src/Illuminate/Foundation/Application.php（644）： Illuminate\Container\Container->make（'App\Http\Kernel'， Array） #3 /home/clients/ffa41f94063541f86a0fe6602a73caa1/myforms/vendor/laravel/framework/src/Illuminate/Container/Container.php（229）： Illuminate\Foundation\Application->make（'App\Http\Kernel'， Array） #4 /home/clients/ffa41f94063 in /home/clients/ffa41f94063541f86a0fe6602a73caa1/myforms/vendor/laravel/framework/src/Illuminate/Container/Container.php第779行

我认为它可能与我的命名空间配置有关，因为我还没有完全理解。

这是我的 composer.json 文件：

{
	"name": "laravel/laravel",
	"description": "The Laravel Framework.",
	"keywords": ["framework", "laravel"],
	"license": "MIT",
	"type": "project",
	"require": {
		"laravel/framework": "5.0.*",
		"illuminate/html": "5.*",
		"barryvdh/laravel-dompdf": "0.5.*",
		"guzzlehttp/guzzle": "~4.0"

	},
	"require-dev": {
		"phpunit/phpunit": "~4.0",
		"phpspec/phpspec": "~2.1"
	},
	"autoload": {
		"classmap": [
			"database"
		],
		"psr-4": {
			"App\\": "myforms/app/"
		}
	},
	"autoload-dev": {
		"classmap": [
			"tests/TestCase.php"
		]
	},
	"scripts": {
		"post-install-cmd": [
			"php artisan clear-compiled",
			"php artisan optimize"
		],
		"post-update-cmd": [
			"php artisan clear-compiled",
			"php artisan optimize"
		],
		"post-create-project-cmd": [
			"php -r \"copy('.env.example', '.env');\"",
			"php artisan key:generate"
		]
	},
	"config": {
		"preferred-install": "dist"
	}
}

我已经做了什么：

• 删除 /vendor 并使用composer install
• composer dump-autoload
• composer update顺便说一句，当我插入composer update

请通知我，如果我应该发布另一个可能有用的文件。

提前感谢您的帮助。
