我在您的文件中没有看到APP_KEY.env。

在命令行中，发出以下 Artisan 命令来生成密钥：

php artisan key: generate

这将为 生成一个随机密钥APP_KEY，编辑完成后.env请在终端中输入以下命令以清除缓存：php artisan config:cache

如果您因供应商文件夹而遇到问题，请执行以下步骤：

composer update --no-scripts 
composer update

• --no-scripts：跳过中定义的脚本的执行composer.json
• Composer update：这将检查项目中所需的库的较新版本。如果找到较新的版本并且它与文件中定义的版本约束兼容composer.json，它将替换以前安装的版本。该composer.lock文件将被更新以反映这些更改。

这两个命令，我们将在我们的项目中重新创建vendor文件夹
