php 工匠不工作並顯示致命錯誤未捕獲錯誤：Class“Illuminate\Foundation\Application”bootsrap\app.php

Question

我試過以下：

 composer install
    composer update
    composer update --no-scripts
    composer dump-autoload

我還刪除了供應商文件夾和 composer.log 但仍然出現同樣的錯誤，請有人幫忙。

它顯示以下錯誤：

PHP Fatal error:  Uncaught Error: Class "Illuminate\Foundation\Application" not found in C:\Users\M Abbas\Documents\Edoc-Editor.com\bootstrap\app.php:14
