Updated the NPM and YO packages then ran the tool to generate the project. I get the following error:

When I open the project in VS 2017 and run the project I get missing packages:

`
Exception: Call to Node module failed with error: Error: Cannot find module 'extract-text-webpack-plugin'
Exception: Call to Node module failed with error: Error: Cannot find module 'awesome-typescript-loader'
`

I then run NPM to install the missing packages then run webpack manually to generate the JS files. This however gives me the following:

I've reinstalled NPM and all packages, cleared out the cache, etc... not sure what else I can do. Any help would be great.

NPM -v : 4.4.4
Node -v : 7.8.0

Thanks.
