藍隊云小課堂：

[Illuminate\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\Database\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\QueryException]

SQLSTATE[HY000] [1045] Access denied for user 'root'@'localhost' (using pas

sword: NO) (SQL: select * from information_schema.tables where table_schema

= laravel_test1 and table_name = migrations)

通常是緩存造成的

在命令行中進入程序根目錄，執行下列語句。

php artisan cache:clear

php artisan config:clear

php artisan serve

然后在執行 php artisan migrate

注意：前提是檢查完了 .env和config/database.php
