TypeError：schema不是构造函数

Question

const mongoose = require('mongoose');

const schema = mongoose.schema;

const marioCharSchema = new schema({

    name: String,
    weight: Number

});

const marioChar = mongoose.model('marioChar', marioCharSchema);

module.exports = marioChar;

Answer 1

二线使用 const schema = mongoose.Schema; javascript是一种区分大小写的语言。

Answer 2

只需将对象导出为对象，并将测试要求作为对象。像这样：

module.exports = {MarioChar};

const assert = require('assert');
const {MarioChar} = require('../models/mariochar');

Answer 3

const Schema = mongoose.Schema;

错了。
