Question

尝试连接数据库时

我的connectig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

我前一段时间只使用过Sequelize，但这就是我初始化它的方式。

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

编辑：

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

我无法连接到Postgres数据库
