Node.js cannot find module 'readable-stream'

Question

I am new to node.js and stuck on the following. Any help will be appreciated:

I am running node.js (0.10.28) on ubuntu (12.10). The code I am working on is:

"use strict";

var  mysql = require('node-mysql'),
connection = mysql.createConnection({
    host: "127.0.0.1",
    user: "user",
    password: "password",
    database: "dbname"
});
    if(connection) { 
    console.log("Query");
    connection.query("select * from client",function(err,res) {
    if(err)console.log(err);
    console.log(res);
});
}   

I get the following error

Error: Cannot find module 'readable-stream'

Answer 1

I got this error for the a long while. Stupidly I hadn't installed gulp... In short this problem occurs when a package is missing.

npm install gulp -g

I would suggest working out which task you are running and then install that.
