我无法连接到 postgres 数据库

Question

尝试连接数据库时

我的连接属性：

const sequelize = new Sequelize("postgres", "postgres", "postgres", {
  dialect: "postgres",
  host: "127.0.0.1",
  port: "5432",
});   

服务器设置： enter image description here

错误：

{ SequelizeConnectionError: ������������ "postgres" �� ������ �������� ����������� (�� ������)
    at connection.connect.err (E:\Dropbox\BigDeal\BigDealExpressJSTest\node_modules\sequelize\lib\dialects\postgres\connection-manager.js:182:24)

    at TCP.onStreamRead [as onread] (internal/stream_base_commons.js:94:17)
  name: 'SequelizeConnectionError',

如何解决？

Answer 1

前段时间我只用过一次Sequelize，但我就是这样初始化的。：

const sequelize = new Sequelize({
    database: 'project-db',
    username: 'postgres',
    password: 'postgres',
    host: 'localhost',
    port: 5432,
    dialect: 'postgres'
});

编辑：

阅读 Sequelize 文档，您的连接方式似乎也应该有效。您确定“postgres”（第一个参数）是现有数据库的名称吗？
