Question

运行下面的代码并尝试为我的应用程序创建注册数据时，我收到一个奇怪的错误。任何人都可能知道这里发生了什么事情？

Unhandled rejection SequelizeConnectionRefusedError: connect ECONNREFUSED 127.0.0.1:5432

User.js

var User = sequelize.define('User', {
  name: {
    type: String,
    required: true
  },
  email: {
    type: String,
    required: true
  },
  password: {
    type: String,
    required: true
  },
  date: {
    type: Date,
    default: Date.now
  }
});

sequelize.sync().then(function () {
  User.create({
       name: 'Steve',
       email: 'email@gmail.com',
       password: '123123',
       date: 02/1/2020
  })
});

Answer 1

当sequelize无法与您的数据库建立连接时，将出现此错误。您可以检查您的数据库是否正在指定的主机和端口上运行吗？

Answer 2

您没有启动数据库或错误的数据库配置，请检查数据库配置：var sequelize = new Sequelize（）或启动数据库

为什么当我尝试创建数据时会引发此错误？
