"尚未设置外观根目录"时在全新结帐后运行"作曲家安装"

Question

我最近有了一台新的PC，并开始迁移我的项目的开发。我已经安装了php，composer和git并进行了检查。我运行 composer install，它将拉动所有依赖项，但然后丢下以下错误：

Writing lock file
Generating optimized autoload files
> IlluminateFoundationComposerScripts::postAutoloadDump
> @php artisan package:discover
PHP Fatal error:  Uncaught RuntimeException: A facade root has not been set. in /home/user/PhpstormProjects/project/vendor/laravel/framework/src/Illuminate/Support/Facades/Facade.php:234

我尝试删除vendor目录和composer.lock文件，然后重新运行composer install，但我会遇到相同的错误。它在我的旧机器上运行良好。我在这里错过了一步吗？

搜索日志后，事实证明这归结为缺少的php7.3-mysql驱动程序。运行sudo apt-get install php7.3-mysql解决了问题！
