问题描述

这是控制台：

我不知道该怎么办，请帮忙：c

顺便说一句，我正在学习 Ben Awad 的 14 小时全栈教程 我的 Postgresql 服务器看起来不错，我知道可能是什么问题，但如果你什么都没有，请告诉它

解决方法

您有受密码保护的 postgres 实例，但您没有提供密码。

import { Options } from '@mikro-orm/core';

const config: Options = {
  migrations: {
    path: path.join(__dirname,"./migrations"),// path to the folder with migrations
    pattern: /^[\w-]+\d+\.[tj]s$/,// regex pattern for the migration files       
  },entities: [Post],dbName : 'lireddit',type: 'postgresql',password: "s3xy",debug: !__prod__,};

export default config;
