php artisan迁移：使用mamp：拒绝用户访问'；根'@'；本地主机'；

我和MAMP有一个Laravel项目。我试图用phpMyAdmin中的MySQL服务器连接到我的数据库。php artisan migrate命令出现以下错误：

  Illuminate\Database\QueryException  : SQLSTATE[HY000] [1045] Access denied for user 'root'@'localhost' (using password: YES) (SQL: select max(`batch`) as aggregate from `migrations`)

  at /Applications/MAMP/htdocs/todoapp/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|

请检查您的数据库连接凭据。看起来您的用户“root”没有访问权限。如果您的用户凭据正确，请检查MySQL配置文件，查找允许的身份验证方法。

检查您的MySQL密码以查找用户根。如果您的数据库凭据不正确，请检查您的mamp安装的db端口谢谢，我自己找到了答案，只是端口号错误，但是，您是否更改了MySQL服务的端口号？因为默认端口在您的示例中是正确的
