Node.js 节点-错误：不支持该方言。支持的方言：mssql、mysql、postgres和sqlite

我有一个节点服务器，数据库是mariadb。当我尝试连接到DB时，出现错误

Error('The dialect ' + this.getDialect() + ' is not supported. 
Supported dialects: mssql, mysql, postgres, and sqlite.');
    ^

Error: The dialect mariadb is not supported. Supported dialects: 
mssql, mysql, postgres, and sqlite.
at new Sequelize (/node_modules/sequelize/lib/sequelize.js:236:15)

我有模块 mariadb:^2.1.1 mariasql:^0.2.6 续集：^4.37.6 mysql2:^1.7.0

如果有人知道的话，请告诉我

提前感谢

我通过将sequelize版本更新为5来解决问题-一直滚动到底部。
