一切都很好，直到我換了電腦。我正在嘗試使用 php artisan migrate 遷移我的資料庫，但出現此錯誤

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')

任何與資料庫互動的嘗試都會帶給我同樣的錯誤

這是我的 .env 設定

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