Generate material setup using ng add fails

What is the expected behavior?

As @jelbourn was presenting yesterday on stage at ngconf, I've tried to install the typical material setup using ng add. This should have resulted in an updated angular.json file, index.html, etc.

What is the current behavior?

Running ng add @angular/material fails with the following 2 lines:

Installing packages for tooling via npm.
Cannot read property 'includes' of undefined

What are the steps to reproduce?

ng new myapp
cd myapp
npm i @angular/material@next @angular/cdk@next --save
ng add @angular/material

Which versions of Angular, Material, OS, TypeScript, browsers are affected?

Angular CLI: 6.0.0-rc.5
@angular/cdk 6.0.0-rc.12
@angular/material 6.0.0-rc.12

Is there anything else we should know?

I like your stuff :)

When i do:

npm install --save @angular/material @angular/cdk

it installs below:

• @angular/material@6.3.2
• @angular/cdk@6.3.2

Then, as per above solutions:

I do:

ng add @angular/material

it throws as below:
