MySQL 与 Sequelize：ER_BAD_DB_ERROR：未知数据库

我正在遵循教程，下面是代码：

var Sequelize = require('sequelize')
var sequelize = new Sequelize('basic-mysql-database.mysql', 'root', 'password', {
    'dialect': 'mysql',
    'host': "localhost",
    "port": "3306"
});

var Todo = sequelize.define('todo', {
    description: {
        type: Sequelize.STRING
    },
    completed: {
        type: Sequelize.BOOLEAN

    }
})

sequelize.sync().then(function(){
    console.log('Everything is synced')

    Todo.create({
        description: 'Walking my dog',
        completed: false
    }).then(function (todo){
        console.log('Finished!')
        console.log(todo)
    })
});

我已经安装了MySQL。当我进入Settings > MySQL它说MySQL Server instance is running

当我跑步时node testDB.js我收到以下错误：

我从未创建过任何架构/表。我确实有 MySQL Workbench，我可以用它创建模式和“Todo”表；然而，我的印象是Sequelize这是即时的吗？我究竟做错了什么？

设置中有一行小字：

相应数据库的凭据

同步将为您创建表，但不会创建数据库。
