mongoose-sequence的AutoIncrementFactory没有生效

"mongoose-sequence": "^5.3.1"

已经按照老师的代码进行编写

打印了一下UserSchema已经有了id这个字段 但接口没有返回

import { Application } from "egg"

import { Schema } from "mongoose"

import * as AutoIncrementFactory from 'mongoose-sequence'

export interface UserProps {

    username: string;

    password: string;

    email?: string;

    nickname?: string;

    picture?: string;

    photoNumber?: string;

    createdAt: Date;

    updatedAt: Date;

}

function initUserModel(app: Application) {

    const AutoIncrement = AutoIncrementFactory(app.mongoose)

    const UserSchema = new Schema({

        username: { type: String, unique: true, required: true },//unique 唯一性  required必须输入

        password: { type: String, required: true },

        email: { type: String },

        nickname: { type: String },

        picture: { type: String },

        photoNumber: { type: String },

    }, {

        timestamps: true /*自动给更新时间和创建时间*/,

        toJSON: {//定义方法 可以直接拿到返回对象使用

            transform(_doc,ret) {

                delete ret.password

                delete ret.__v

            }

        }

    })

    UserSchema.plugin(AutoIncrement, { inc_field: 'id', id: 'users_id_counter' })

    // return app.mongoose.model<UserProps>('User', UserSchema)

    return app.mongoose.model<UserProps>('User', UserSchema);

}

export default initUserModel;

尝试过的解决方式：

1.删除node_modules和package-lock.json重新npm install

2.关闭vscode重启
