Build Error

[General-Afify]

Hi,

When importing the theme using:
@import "node_modules\@progress\kendo-theme-material\scss\all";
The below error appears:

events.js:160
throw er; // Unhandled 'error' event
^
Error: node_modules\@progress\kendo-theme-material/modules\@progress\kendo-theme-default\scss\mixins_button.scss
Error: ".k-button:not(.k-no-focus):focus" failed to @extend "%appearance_focused-button".
The selector "%appearance_focused-button" was not found.
Use "@extend %appearance_focused-button !optional" if the extend should be able to fail.
on line 62 of node_modules\@progress\kendo-theme-material\modules@progress\kendo-theme-default\scss\mixins_button.scss

mixin appearance_focused-button { @extend %appearance_focused-button };
------------------------------------------^

We are not aware of this problem, and I could not reproduce this in Angular-CLI. Please open a support ticket and provide a sample project that illustrates the problem.
