找不到类“Illuminate\Http\Response”答案

【问题标题】：Class 'Illuminate\Http\Response' not found找不到类“Illuminate\Http\Response”
【发布时间】：2021-01-03 02:56:12
【问题描述】：

我的应用后端突然停止工作，返回 500 HTTP 错误，并在 laravel.log 中出现此错误：

[2020-09-16 12:28:15] local.ERROR: Uncaught Error: Class 'Illuminate\Http\Response' not found in /home/.../vendor/laravel/framework/src/Illuminate/Foundation/Exceptions/Handler.php:424
[2020-09-16 12:28:19] local.ERROR: Class 'Illuminate\Http\Response' not found {"exception":"[object] (Symfony\\Component\\Debug\\Exception\\FatalThrowableError(code: 0): Class 'Illuminate\\Http\\Response' not found at /home/../vendor/laravel/framework/src/Illuminate/Routing/Router.php:751)

Laravel 版本是 5.8.37

有谁知道哪里出了问题？

我已经尝试过 chmod -R 777 storage/、php artisan cache:clear、php artisan config:clear 和 composer dump-autoload，都没有成功。

提前谢谢你！

编辑：删除供应商文件夹并运行以下命令修复了问题，但是我注意到在 composer dump-autoload 期间出现了一些错误。

composer install

以下是出现的错误：

谢谢！

【问题讨论】：

你能证明一段代码正是导致这个错误的原因吗？
问题是我没有更改我的控制器中的任何内容，并且错误日志显示问题出在 /vendor/ 中，而不是在我的控制器中。知道发生了什么吗？
你能不能运行 composer dump-autoload，或者这可能是旧错误
@MuhammadTariq 他们说他们已经跑过了
您可以删除供应商文件夹并运行composer install。也许它会工作。

标签： php laravel composer-php

【解决方案1】：

您的 vendor 文件夹似乎有问题，因此请删除旧的 vendor 文件夹

运行这个 cmd composer install 然后composer dump-autoload

这里composer install 将安装您项目的所有依赖项 composer dump-autoload 将加载处理这些依赖项所需的所有文件

【讨论】：

composer install 将转储自动加载
非常感谢您的解决方案！我发布了一些在 composer dump-autoload 期间出现的错误，知道我能做些什么来解决这些问题吗？
