推荐答案

您可以使用本机mongo驱动程序的

You can use the native mongo driver's Admin#buildInfo method for that via your Mongoose connection:

var mongoose = require('mongoose');

mongoose.connect('mongodb://localhost/test', function(err){
  var admin = new mongoose.mongo.Admin(mongoose.connection.db);
  admin.buildInfo(function (err, info) {
     console.log(info.version);
  });
});
