I have found some posts describing the steps for setting this up but when I follow them I receive an error: cannot find module 'cucumber'. I have cucumber and protractor and protractor-cucumber installed global and can execute them individually but not when trying to execute Protractor with a framework of cucumber.

The config file I am using is as follows:

var env = require('./environment.js');

// A small suite to make sure the cucumber framework works.
exports.config = {
    seleniumAddress: env.seleniumAddress,

    framework: 'cucumber',

    // Spec patterns are relative to this directory.
    specs: [
      '../app/modules/auth/html/cucumber/*.feature'
    ],

    capabilities: env.capabilities,

    baseUrl: env.baseUrl,

    cucumberOpts: {
      require: '../app/modules/auth/html/cucumber/stepDefinitions.js',
      tags: '@dev',
      format: 'summary'
    }
};

Any suggestions what I can try in order to resolve the issue?

It's still likely that cucumber isn't installed globally.

Try this on your command line:

node
> require('cucumber')

If that complains about cucumber not being found, then you didn't install cucumber globally. Otherwise, can you paste the stacktrace.

I entered the command

npm install cucumber

and the issue is resolved.

I've had a similar issue on Windows 7, that was resolved by adding an environment variable so that Node could locate modules installed with the -g flag, as per Nodejs cannot find installed module on Windows?
