Laravel Console PDOException

Question

当我运行以下命令时：

php artisan make:console foobar

我收到以下错误：

{"error":{"type":"PDOException","message":"SQLSTATE[HY000]
 [2002] No such file or
 directory","file":"\/Users\/username\/Projects\/Projectname\/vendor\
/laravel\/framework\/src\/Illuminate\/Database\
/Connectors\/Connector.php","line":47}}

第47行的Connector.php：

return new PDO($dsn, $username, $password, $options);

知道这个错误可能来自哪里？
