There is not much documentation about this yet as Mongoose 5 is in release candidate stage but with mongoose 5 you don't need to provide useMongoClient option. Mongoose 5 is using Mongo client by default. So just remove this option.

关于这一点没有太多的文档，因为Mongoose 5正在发布候选阶段，但是在Mongoose 5中，您不需要提供useMongoClient选项。Mongoose 5在默认情况下使用Mongo客户端。所以移除这个选项。

mongoose 5 doesn't require useMongoClient anymore.

猫鼬5不再需要我们的客户了。

mongoose.connect('mongodb://localhost/DB_name');

is enough. You can check for the documentation of "Mongoose 5" here

就足够了。您可以在这里查看“Mongoose 5”的文档。

const mongoose = require('mongoose');
mongoose.connect('mongodb://127.0.0.1:27017/qunar', { useMongoClient: true });
mongoose.Promise = global.Promise;
module.exports = mongoose

Delete the first line of code { useMongoClient: true } and then restart the server

删除第一行代码{useMongoClient: true}然后重新启动服务器。
