SQLSTATE[HY000][2002]php_network_getaddresses:getaddrinfofailed:没有这样的主机是已知的。（Laravel8迁移错误）

当我运行命令 php artisan migrate 时，在新安装了 livewire 的新 laravel8 jetstream 之后，它在我的终端上给出了错误

  SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo failed: No such host is known.  (SQL: select * from information_schema.tables where table_schema = lweb and table_name = migrations and table_type = 'BASE TABLE')
