node.js - cannot find module "lodash"

Question

Today I tried to learn more about Google Web Starter Kit so I followed these instructions and after a lot of fight and problem I just tried to start a local server (the first task we’ll look at is: $ gulp serve.) and received this error:

C:gwsk>gulp serve

Error: Cannot find module 'lodash'
    at Function.Module._resolveFilename (module.js:338:15)
    at Function.Module._load (module.js:280:25)
    at Module.require (module.js:364:17)

Honestly I'm completely lost here, so any help is pretty welcome. I'm new to node.js, to gulp, I just wanted it to try GWSK but turn into a headache :(... I'm a web designer not developer....

Be sure to install lodash in the required folder. This is probably your C:gwsk directory.

If that folder has a package.json file, it is also best to add --save behind the install command.

$ npm install lodash --save

The package.json file holds information about the project, but to keep it simple, it holds your project dependencies.

The save command will add the installed module to the project dependencies.

If the package.json file exists, and if it contains the lodash dependency you could try to remove the node_modules folder and run following command:

$ npm cache clean    
$ npm install

The first command will clean the npm cache. (just to be sure) The second command will install all (missing) dependencies of the project.

Hope this helps you understand the node package manager a little bit more.
