Question

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。在托管服务的服务器上传整个项目后，我在浏览器和SSH shell上都出现了这些错误。

致命错误：未捕获的异常＆＃39; ReflectionException＆＃39;消息＆＃39; Class App \ Http \ Kernel不存在＆＃39;在/home/clients/ffa41f94063541f86a0fe6602a73caa1/myforms/vendor/laravel/framework/src/Illuminate/Container/Container.php:779 堆栈跟踪：＃0 /home/clients/ffa41f94063541f86a0fe6602a73caa1/myforms/vendor/laravel/framework/src/Illuminate/Container/Container.php(779）：ReflectionClass-＆gt; __ construct（＆＃39; App \ Http \ Kernel＆＃39 ;）＃1 /home/clients/ffa41f94063541f86a0fe6602a73caa1/myforms/vendor/laravel/framework/src/Illuminate/Container/Container.php(659）：Illuminate \ Container \ Container-＆gt; build（＆＃39; App \ Http \内核＆＃39;，数组）＃2 /home/clients/ffa41f94063541f86a0fe6602a73caa1/myforms/vendor/laravel/framework/src/Illuminate/Foundation/Application.php(644):Illuminate \ Container \ Container-＆gt; make（＆＃39） ; App \ Http \ Kernel＆＃39;，Array）＃3 /home/clients/ffa41f94063541f86a0fe6602a73caa1/myforms/vendor/laravel/framework/src/Illuminate/Container/Container.php(229):Illuminate \ Foundation \ Application-＆gt;在/home/clients/ffa41f94063541f86a0fe6602a73caa1/myforms/vendor/laravel/framework/src/Illuminate/Container/Container.php中制作（＆＃39; App \ Http \ Kernel＆＃39;，数组）＃4 / home / clients / ffa41f94063在779号线上

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：

＆＃13;

{
	"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"
	}
}

＆＃13;

我已经做过的事情：

删除/供应商并使用composer install
composer dump-autoload
composer update 顺便说一句，我在插入composer update

如果我要发布另一个可能有用的文件，请通知我。

提前感谢您的帮助。

Answer 1

在composer.json中更改：

`  .page-wrapper {
   min-height: 100vh;
   position: relative;
  }

  footer {
  background-color: #f0f;
  position: absolute;
  bottom: 0;
  width: 100%
 }

 .longer {
   height: 50px;
   background-color: #ddd;
 }`

为：

 "psr-4": {
        "App\\": "myforms/app/"
    }

在服务器上的源目录中，运行"psr-4": { "App\\": "app/" }，然后composer update

Laravel中的PSR-4查找相对于项目根目录的命名空间

Answer 2

在我的情况下，composer.json缺少右括号“ {}”，并且“ psr-4”所在的行位于错误的json段中。

检查composer.json是否正确对齐“ psr-4”，它应该是“自动加载”部分的子级。
删除供应商
作曲家安装

好

Answer 3

检查console/kernel.php是否在app文件夹内，如果不是，则可能在您的laravelApp文件夹内。

如果是，请将console/kernel.php移至app文件夹。
