Question

我正在使用Angular for ui用Electron开发一个桌面应用程序，我想使用sequelize-typescript连接到数据库，但是创建sequelize实例会出现以下错误。可以在sangelize中使用sequelize-typescript吗？

Error-capture

TypeError: sequelize_typescript__WEBPACK_IMPORTED_MODULE_3__.Sequelize is not a constructor
at AppComponent.index4 (app.component.ts:126)
at new AppComponent (app.component.ts:29)
at NodeInjectorFactory.AppComponent_Factory [as factory] (app.component.ts:136)
at getNodeInjectable (core.js:6025)
at instantiateRootComponent (core.js:12788)
at createRootComponent (core.js:26484)
at ComponentFactory$1.create (core.js:34106)
at ApplicationRef.bootstrap (core.js:43103)
at core.js:42691
at Array.forEach (<anonymous>)

我这样导入：

Import-capture

import Person from './lib/model/Person';
import { Component, OnInit } from '@angular/core';
import { Sequelize, DataType } from 'sequelize-typescript';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.scss']
})
export class AppComponent implements OnInit {
  title = 'wi2';

  ngOnInit() {

    const database = new Sequelize({
      database: 'test1',
      dialect: 'postgres',
      username: 'test',
      password: 'test'
    });
    database.authenticate()
      .then(() => console.log("aut"))
      .catch(() => console.log("no aut"))
      
    database.addModels([Person])
      .then(() => console.log("models added"))
      .catch((err) => console.log(err));
  }


  constructor() { }
}
