mysql – SequelizeConnectionError：客户端不支持服务器请求的身份验证协议;考虑升级MariaDB客户端

我在nodejs(v6.11.0)应用程序上使用Sequelize版本4.3.0,使用readline 5.2,使用Mariadb(mysql Ver 15.1 distrib 10.0.29-MariaDB,debian-linux-gnu(i686))
)在Ubuntu 16.04上.
当应用程序启动并调用函数时：
 Sequelize.sync();
然后sequelize连接管理器抛出以下错误：

Unhandled rejection SequelizeConnectionError: Client does not support authentication protocol requested by server; consider upgrading MariaDB client

我更新了mariadb-server和mariadb-client,但问题已经存在！

有人可以帮我解决这个问题吗？

解决方法:

我找到了答案：

登录MySQL命令行并编写以下命令：

use MysqL;

更新用户集authentication_string = password(”),plugin =’MysqL_native_password’,其中user =’root’;
