EDIT: Don't add to your angular-cli.json files script section. This is not needed!

You seem to have it right there, just to make sure, here are the steps with how i can reproduce it working on one of my projects:

• stop the current ng serve
• do npm install lodash --save and npm install @types/lodash --save-dev
• In the controler do your import * as _ from 'lodash';
• Use it like this: console.log(_.chunk(['a', 'b', 'c', 'd'], 2));
• ng serve again
