解决方案

从警告消息中，我发现这里有很好的记录。

它说，将设置从server、replset和mongos键向上移动到对象的顶层。

// The options inside the `server` attributes are moved to its parents.
// Same happens to `replset` and `mongos`
// Change this
mongoose.connect( 'mongodb://localhost/db',
  {
    useMongoClient: true,
    server: {
      poolSize: 2
    },
    promiseLibrary: global.Promise
  }
);

// To this
mongoose.connect( 'mongodb://localhost/db',
  {
    useMongoClient: true,
    poolSize: 2,
    promiseLibrary: global.Promise
  }
);

有关更多信息，请参阅mongoose 文档中的选项。
