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

Question

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

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!

谁能帮我解决这个问题？
