Repro steps.

I started your Tour of heroes tutorial. Step 3 had me run ng generate component heroes. This caused the compile to fail with error TS2304: Cannot find name 'ViewEncapsulation'. The tutorial didn't expect this line at the bottom of the component definition.
encapsulation: ViewEncapsulation.None
I had to manually add - import { ViewEncapsulation } from '@angular/core';
to fix the error.

The log given by the failure.

error TS2304: Cannot find name 'ViewEncapsulation'

Desired functionality.

Mention any other details that might be useful.

import { ViewEncapsulation } from '@angular/core'
this will fix the problem.

I know, it is in the repro steps. I'm just saying that it should generate files that compile.
