mongoose - TS2351 : Cannot use 'new' with an expression whose type lacks a call or construct signature. Mongoose

Question

不确定我做错了什么，但我有这个类/模块:

import * as Mongoose from 'mongoose';
import * as _ from 'lodash';
import * as Promise from 'bluebird';
import { db } from '../lib/database';

let mongoose = Mongoose;

mongoose.Promise = Promise;


export class BaseModel  {

    constructor(schemaObj: {}, modelName: string, statics?: {}) {
      let Schema = new mongoose.Schema(schemaObj)

      Schema.statics.list = function () {
        return this.find()
      }

      Schema.statics.save = function (dataObj) {
        return this.save(dataObj)
      }

      if (statics) {
        for (let key in statics) {
          Schema.statics[key] = statics[key];
        }
      }
      
      return mongoose.model(modelName, Schema);
    }
    
}

let schema = {
  title:  String,
}

let Message = new BaseModel(schema, 'message');

let j = new Message({title: 'Hello World'}).save().then(function (res) {
  console.log(res);
})

一切实际上都有效，但 TypeScript 正在提示:

TS2351: Cannot use 'new' with an expression whose type lacks a call or construct signature.

我知道我错过了一些东西，但我不知道是什么。

Answer 1

尝试在导入 mongoose 时删除 * as。所以它会变成
从 'mongoose' 导入 Mongoose；
