【问题描述】：

我一直在使用 Sequelize 检查 MariaDB 的连接性。

const Sequelize = require('sequelize');

// Setting up database (MariaDB) connection
const sequelize = new Sequelize('dbName', 'usr', 'pass', 
  host: 'localhost',
  dialect: 'mariadb'
);

但我收到以下错误：

/home/lt-196/api/node_modules/sequelize/lib/sequelize.js:236
        throw new 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.

【参考方案1】：

玛丽亚数据库 为了与 MariaDB 兼容，您必须安装包 mariasql@0.1.20 或更高版本。 配置需要如下所示：

var sequelize = new Sequelize('database', 'username', 'password', 
  dialect: 'mariadb'
)

或者试试这个：

MariaSQL：https://www.npmjs.com/package/mariasql

一个 node.js 绑定到 MariaDB 的非阻塞（MySQL 兼容）客户端库。

var Client = require('mariasql');

var c = new Client(
  host: '127.0.0.1',
  user: 'foo',
  password: 'bar'
);

c.query('SHOW DATABASES', function(err, rows) 
  if (err)
    throw err;
  console.dir(rows);
);

c.end();

推荐使用 MariaSQL。

【讨论】：

MariaSQL 正在工作，谢谢，但第一个选项会更好，但它不工作。

你可以使用'mysql'作为方言。

    yarn add mariadb
    yarn add sequelize@next

  const Sequelize = require('sequelize'),
    sequelize = new Sequelize(process.env.db_name, process.env.db_user, process.env.db_pass, 
    dialect: 'mariadb',
