【问题描述】：
我正在尝试将Mongoose 与 typescript 2.2.1、express 4.15.2 和 node v7.7.2 一起使用，但是当我尝试连接到 mongodb 时，它会引发此错误：
TypeError: "listener" argument must be a function

at Mongoose.connect (/home/fabian/Projects/Huis-Pils/node_modules/mongoose/lib/index.js:242:47)
代码：
import * as mongoose from "mongoose";
(<any>mongoose).Promise = global.Promise;
mongoose.connect('mongodb://localhost/test');
我就是想不通我做错了什么。
