Laravel错误'ReflectionException' - 'Class App\Http\Kernel does not exist'

我试图接受一年后在学校开发的laravel项目，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，我在浏览器和SSH shell上都出现了这些错误 .

致命错误：/home/clients/ffa41f94063541f86a0fe6602a73caa1/myforms/vendor/laravel/framework/src/Illuminate/Container/Container.php:779堆栈中未捕获的异常'ReflectionException'，消息'Class App \ Http \ Kernel'不存在'跟踪：＃0 /home/clients/ffa41f94063541f86a0fe6602a73caa1/myforms/vendor/laravel/framework/src/Illuminate/Container/Container.php(779）：ReflectionClass - > __ construct（'App \ Http \ Kernel'）＃1 / home /客户/ 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'，Arra y）第779行/home/clients/ffa41f94063541f86a0fe6602a73caa1/myforms/vendor/laravel/framework/src/Illuminate/Container/Container.php中的＃4 / home / clients / ffa41f94063

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/供应商并使用 composer install 进行新安装

• composer dump-autoload

• composer update 顺便说一下，插入 composer update 时收到错误

如果我应该发布另一个可能有用的文件，请通知我 .

在此先感谢您的帮助 .
