TypeError: sequelize.import is not a function

Question

我运行遇到一个错误，我找不到解决方法：

C:\Users\student\Desktop\project\src\models\index.js:17
  User: sequelize["import"]('./user'),
                           ^

[nodemon] app crashed - waiting for file changes before starting...

代码如下：

import Sequelize from 'sequelize';

const sequelize = new Sequelize(
  process.env.DATABASE,
  process.env.DATABASE_USER,
  process.env.DATABASE_PASSWORD,
  {
    dialect: 'postgres',
  },
);

const models = {
  User: sequelize.import('./user'),
  Message: sequelize.import('./message'),
};

Object.keys(models).forEach(key => {
  if ('associate' in models[key]) {
    models[key].associate(models);
  }
});

export { sequelize };

export default models;

    "@babel/core": "^7.12.9",
    "@babel/node": "^7.12.6",

    "sequelize": "^6.3.5",

我不确定解决问题的正确方向。如果您运行遇到过类似的问题，我们将不胜感激。我已经添加了开发依赖项以防万一。

Answer 1

我相信当他们移动到 6 时有些东西发生了变化....看看这个 link.. 或者你可以按照这个线程

中的建议回到 5.22.3

我目前使用的是 5.22.3，我的语法和你的完全一样，而且工作正常，但即将升级到 6，也需要解决这些问题..

Answer 2

这将对续集 6 起到作用

import Sequelize from 'sequelize';

const sequelize = new Sequelize(
  process.env.DATABASE,
  process.env.DATABASE_USER,
  process.env.DATABASE_PASSWORD,
  {
    dialect: 'postgres',
  },
);

const models = {
  User: require('./user')(sequelize, Sequelize),
  Message: require('./message')(sequelize, Sequelize),
};

Object.keys(models).forEach(key => {
  if ('associate' in models[key]) {
    models[key].associate(models);
  }
});

export { sequelize };

export default models;
