我正在嘗試使用 laravel 配置 msql db，但遇到了一個奇怪的問題。在線搜索后，我仍然沒有完成遷移。在我的 .env 我有DB_CONNECTION=mysqlDB_HOST=127.0.0.1DB_PORT='%db_port%'DB_DATABASE='forge'DB_USERNAME='root'DB_PASSWORD='password'所以改變.ENV我做了以后php artisan cache:clear，然后 php artisan config:cache，該運行后，php artisan migrate我得到了   Illuminate\Database\QueryException  : SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo failed: nodename nor servname provided, or not known (SQL: select * from information_schema.tables where table_schema = %db_name% and table_name = migrations)  at /Users/p/Documents/Project/hub-family-server/vendor/laravel/framework/src/Illuminate/Database/Connection.php:664    660|         // If an exception occurs when attempting to run a query, we'll format the error    661|         // message to include the bindings with SQL, which will make this exception a    662|         // lot more helpful to the developer instead of just the database's errors.    663|         catch (Exception $e) {  > 664|             throw new QueryException(    665|                 $query, $this->prepareBindings($bindings), $e    666|             );    667|         }    668|   Exception trace:  1   Doctrine\DBAL\Driver\PDOException::("SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo failed: nodename nor servname provided, or not known")      /Users/p/Documents/Project/hub-family-server/vendor/doctrine/dbal/lib/Doctrine/DBAL/Driver/PDOConnection.php:31  2   PDOException::("PDO::__construct(): php_network_getaddresses: getaddrinfo failed: nodename nor servname provided, or not known")      /Users/p/Documents/Project/hub-family-server/vendor/doctrine/dbal/lib/Doctrine/DBAL/Driver/PDOConnection.php:27  Please use the argument -v to see more details.所以我不再確定發生了什么，我也確實更新了 dbal，composer require doctrine/dbal但這沒有做任何事情。有人可以幫助我了解發生了什么，謝謝。
