Answer 1

您正在使用带有三个参数的model函数，这不是一个有效的声明。

试着写这个

user.js

'use strict';
var mongoose = require('mongoose');
var UserSchema = mongoose.Schema({
    email              : String,
    password           : String,
    isFacebookAccount  : Boolean
});
UserModel = mongoose.model("Users", UserSchema);
module.exports = UserModel;

你只需要在运行程序时连接数据库，那么这个错误就不会发生
