Angular CLI version 9 (used to create Angular 9 projects) now picks up style from schematics instead of styleext. Use the command like this:
ng config schematics.@schematics/angular:component.style scss
and the resulting angular.json shall look like this

"schematics": {
   "@schematics/angular:component": {
      "style": "scss"
    }
  }

Other possible solutions & explanations:

To create a new project with angular CLI with sass support, try this:

ng new My_New_Project --style=scss 

You can also use --style=sass & if you don't know the difference, read this short & easy article and if you still don't know, just go with scss & keep learning.

If you have an angular 5 project, use this command to update the config for your project.

ng set defaults.styleExt scss

For Latest Versions

For Angular 6 to set new style on existing project with CLI:

ng config schematics.@schematics/angular:component.styleext scss

Or Directly into angular.json:

"schematics": {
      "@schematics/angular:component": {
      "styleext": "scss"
    }
}
