问题描述

我通过 composer 安装了 Guzzle，但收到了这个错误，

I installed via composer the Guzzle and i received this error,

> @php artisan package:discover
PHP Fatal error:  Uncaught Error: Class 'IlluminateFoundationApplication' not found in /home/vagrant/PROJ/memo/laravel_project/bootstrap/app.php:14
Stack trace:

Script @php artisan package:discover handling the post-autoload-dump event returned with error code 255

这之前可以工作，现在我检查了 DIR 路径，一切正常.我还尝试了 composer dump-autoload、composer update、删除 composer.lock 和 vendor、composer install

this was working before, and now i checked the DIR path and it's all ok. I also tried composer dump-autoload, composer update, removing composer.lock and vendor, composer install

推荐答案

删除 vendor 文件夹和 composer.lock.

Delete vendor folder and composer.lock.

之后

作曲家安装

然后

作曲家更新 --no-scripts

试试这个，这将解决你的错误.注意:请确保您拥有 composer.json 中的所有包.

Try this, this will solve your error. Note: Please make sure you have all packages in composer.json.
