带有Sequelize的MySQL：ER_BAD_DB_ERROR：未知数据库

我正在关注一个教程,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.当我进入设置> MySQL,并说MySQL Server实例正在运行

当我运行节点testDB.js时,出现以下错误：

Unhandled rejection SequelizeConnectionError: ER_BAD_DB_ERROR: Unknown database 'basic-mysql-database.mysql'

我从未创建任何架构/表.我确实有MySQL Workbench,可以用来创建模式和“ Todo”表；但是,我的印象是Sequelize可以即时运行吗？我究竟做错了什么？

解决方法:

设置中有一条很小的线,上面写着：

The credentials for the respective database

Sync会为您创建表,但是不会创建数据库.
