一切都很好，直到我换了电脑。我正在尝试使用 php artisan migrate 迁移我的数据库，但出现此错误

SQLSTATE[HY000] [2002] No such file or directory (SQL: select * from information_schema.tables where table_schema = grain and table_name = migrations and table_type = 'BASE TABLE')

任何与数据库交互的尝试都会给我带来同样的错误

这是我的 .env 配置

DB_CONNECTION=mysql
    DB_HOST=127.0.0.1
    DB_PORT=3306
    DB_DATABASE=grain
    DB_USERNAME=root
    DB_PASSWORD=
