我正在使用Laravel 6.*和Mysql 8.0.18。我正在使用Mysql，因此我将.env和数据库文件中的端口从3306更改为3308。我将拉拉维尔路由为 127.0.0.1：8000。它没有使用创建的数据库进行更新，并显示错误，默认数据库Laravel未找到，如下所示-
Illuminate\Database\QueryException SQLSTATE[HY000] [1049] 未知数据库 'laravel' (SQL： 从students中选择 * (
请帮助我找出我犯错的地方。提前感谢您的帮助。
只是为了让每个人都可以在不查看评论的情况下看到答案。
在 laravel 中更改数据库设置后，您需要记住执行以下命令：
php artisan cache:clear
