@ngtools crashes when using scss with ViewEncapsulation.None

[qdouble]

Please provide us with the following information:

OS?

Mac OSX (Sierra)

Versions.

Using webpack repo from the test directory: https://github.com/angular/angular-cli/tree/master/tests/e2e/assets/webpack/test-app

Repro steps.

If you set ViewEncapsulation.None any component, like right here: https://github.com/qdouble/show-encapsulation-error/blob/master/app/app.component.ts#L9 and then run the webpack command it will crash. You can download the repo from that link if you want, the only thing that I changed is adding ViewEncapsulation.None

Might be related to angular/angular#11408

I hope this will be fixed soon.

Is someone still working on that problem?

[kuldeepkeshwar]

any workaround for this ?

[debben]

For places where ViewEncapsulation.None was used, I've removed the styles altogether and just placed a line import 'styles!./path/to/style.scss' above the component. When using just-in-time compilation, Angular was pretty much just doing the same thing as the style loader I think and injecting a new style tag with the contents in the head section.

This bug has also had me reevaluating the styles I was using in components with ViewEncapsulation.None to determine what can be promoted to just a global stylesheet and what should stay. The styles that are component specific I'm working to change to use ViewEncapsulation.Emulated.

@DzmitryShylovich Yes it's related to that issue in the code generator.

In the CLI itself I'm going to move the generated code to its own directory. A PR should come soon to do just this. That way we will avoid the issue. There will not be a change in the configuration so you guys should not notice anything different (other than the bug being fixed).

Actually I retract my previous statement. This does not seem related to that issue, but rather might be a bug in the ngtools itself when using outside of the CLI, and using genDir that's not the basePath. I'm trying to repro locally and investigating further.
