Question

我当前在服务器端设置NodeJS，ExpressJS，Sequelize和PostgresSQL

我的代码设置如下：-

我的config/config.js文件中有以下内容

username: "Eexpress-mvp-dbuser",
    password: "123",
    database: "mvp-db",
    host: "127.0.0.1",
    dialect: "postgress",
    port: 5432,
    operatorsAliases: false

在我的迁移文件中，我设置了以下代码

  up: (queryInterface, Sequelize) => {
    return queryInterface.createTable("Leads", {
      id: {
        allowNull: false,
        autoIncrement: true,
        primaryKey: true,
        type: Sequelize.INTEGER
      },
      email: {
        type: Sequelize.STRING
      },
      createdAt: {
        allowNull: false,
        type: Sequelize.DATE
      },
      updatedAt: {
        allowNull: false,
        type: Sequelize.DATE
      }
    });
  },
  down: (queryInterface, Sequelize) => {
    return queryInterface.dropTable("Leads");
  }
};```

Sequelize CLI [Node: 8.11.3, CLI: 5.5.0, ORM: 5.12.3]

Loaded configuration file "config\config.js".

ERROR: Dialect needs to be explicitly supplied as of v4.0.0

Answer 1

您的方言名称有误：

使用dialect: "postgres"

代替dialect: "postgress"

还请确保安装以下依赖项：

npm install pg --save
npm install pg-hstore --save

最后，您需要创建一个数据库。 Sequelize不能满足您的需求

方言需要明确提供
