不能使用 mongoosastic 函数 .x 不是函数

Question

我尝试用 npm 添加 mongoosastic @types 但是没有用，我怎样才能让它识别函数？ (.search() 也不起作用)

VS Code 描述的错误：

模块"c:/Users/joche/Desktop/Proyectos/E-Commerce/Backend/node_modules/mongoosastic/lib/mongoosastic" 找不到模块 'mongoosastic' 的声明文件。 'c:/Users/joche/Desktop/Proyectos/E-Commerce/Backend/node_modules/mongoosastic/lib/mongoosastic.js' 隐式具有 'any' 类型。如果存在，请尝试 npm install @types/mongoosastic 或添加包含 declare module 'mongoosastic';ts(7016)

的新声明 (.d.ts) 文件

这是我的代码：

const express = require("express");
const bodyParser = require("body-parser");
const mongoose = require("mongoose");
const mongoosastic = require("mongoosastic");
const Schema = mongoose.Schema;
const app = express();

app.use(bodyParser.urlencoded({
    extended: true
}));

app.use(express.static('public'));


mongoose.connect("mongodb://localhost:27017/gaminghard", {useNewUrlParser: true});

const ProductSchema = mongoose.Schema({
    _id: mongoose.Schema.Types.ObjectId,
    name: { type:String, es_indexed:true },
    category: String,
    brand: String,
    model: { type:String, es_indexed:true },
    desc: { type:String, es_indexed:true },
    price: Number,
    stock: Number,
    weight: Number,
    img: String,
    quantityToBuy: Number
},
{
    collection: 'Products'
});

const Product = mongoose.model("Product", ProductSchema);

ProductSchema.plugin(mongoosastic, {
    hosts: [
        "localhost:9200"
    ]
});

Product.createMapping(function(err, mapping){
    if(err){
        console.log("error creating mapping");
        console.log("err");
    }else{
        console.log("Mapping successfully created");
        console.log(mapping);
    }
});

app.listen(3000, function(){
    console.log("Server started listening on port 3000");
});

Nodemon 错误：

C:\Users\joche\Desktop\Proyectos\E-Commerce\Backend\server.js:60
Product.createMapping(function(err, mapping){
        ^

    "mongoose": "^5.7.12",
  }
}

编辑：尝试添加 .d.ts 文件，VS Code 错误消失但仍无法编译源代码。

这里自答，不得不搬家

ProductSchema.plugin（猫鼬，{ 主持人：[ "localhost:9200" ] });

以上

const Product = mongoose.model("Product", ProductSchema);

因为我随后在没有使用之前应用的插件的情况下使用 Product，这没有意义。
