Please help me to solve this problem.

the code in privatePro/app.js is

var db = require('diskdb');

db.connect('./examples/db', ['articles','comments','users']);

var article1 = {
    title : 'diskDB rocks',
    published : 'today',
    rating : '5 stars'
}

var article2 = {
    title : 'diskDB rocks',
    published : 'yesterday',
    rating : '5 stars'
}

var article3 = {
    title : 'diskDB rocks',
    published : 'today',
    rating : '4 stars'
}
db.articles.save([article1, article2, article3]);

var articleComments = {
    title: 'diskDB rocks',
    published: '2 days ago',
    comments: [{
        name: 'a user',
        comment: 'this is cool',
        rating: 2
    }, {
        name: 'b user',
        comment: 'this is ratchet',
        rating: 3
    }, {
        name: 'c user',
        comment: 'this is awesome',
        rating: 2
    }]
}

db.comments.save(articleComments);



var printFruits = function() {
    console.log(db.articles.find());
}

// To test the app locally
 //npm publishprintFruits(); // << uncomment this
// and run
// $ node app.js

exports.printFruits = printFruits;

Answer 1

Node "require" function will look in node_modules by default, try

require('privateProj');

and rename node_modules/privateProj/app.js to node_modules/privateProj/index.js

Also change your module code (privateProj code) from:

exports.printFruits = printFruits;

to

module.exports = printFruits;

Also just noticed you're exporting the function, in your myApp.js change

pp.printFruits();

to just

pp();

First - you don't need to set full path to npm module, you can just require('moduleName').
Second (and main issue in your case) - you set absolute path and that's why your script can't find it.
So use just require(moduleName)
