The Yeoman custom generator is failing to load dependencies specified in the package.json file

I've developed a custom Yeoman generator. In the index.js file, I am trying to replace some text within certain files. I added the dependency replace in the package.json, and then when I try to use require('replace') in index.js during the generator execution, it throws an error saying 'Cannot find module 'replace''. I have experimented with different modules from NPM, but none of them seem to load properly - all resulting in failures due to not finding the module.

The related section in package.json

  "dependencies": {
    "replace": "~0.2.9",
    "yeoman-generator": "~0.16.0",
    "chalk": "~0.4.0"
  },

Snippet from index.js

'use strict';
var util = require('util');
var path = require('path');
var yeoman = require('yeoman-generator');
var chalk = require('chalk');
var replace = require('replace');

var MyGenerator = yeoman.generators.Base.extend({
    init: function () {
        this.pkg = require('../package.json');

For some reason, the generator fails at the point where it requires 'Replace'. It's interesting to note that Chalk and Yeoman Generator load without any issues, despite being loaded in the same manner.

What could be causing my additional modules to fail loading?

Have you executed the command npm install after inserting that line into the package.json file yourself? It is recommended to add a package by running: npm install --save _package_. This will fetch the most recent version and include it in your package.json.
