What is this crazy error in node js - js-bson: Failed to load c++?

Question

Node.js

I wanted to learn a new one called. Executed the script for checking the connection to the database

var MongoClient = require('mongodb').MongoClient
    , assert = require('assert');

// Connection URL
var url = 'mongodb://localhost:27017/party';
// Use connect method to connect to the Server
MongoClient.connect(url, function(err, db) {
    assert.equal(null, err);
    console.log("Connected correctly to server");

    db.close();
});

As a result, it throws an error
{ [Error: Cannot find module '../build/Release/bson'] code: 'MODULE_NOT_FOUND' }
js-bson: Failed to load c++ bson extension, using pure JS version
and then, as it were, executes. How is this to be understood

Answer 1

Failed to load c++ bson extension, using pure JS version

That's how to understand. Your module complains that you do not have a fast and convenient module for working with BSON written in pluses installed and therefore it will use a slow JS implementation.
