[luck17291]

Hi
I am configuring stylePreprocessorOptions includePaths in CLI but it does not work
"stylePreprocessorOptions": {
"includePaths": [
"",
"environments/app1"
]
},
get error:
ERROR in ./node_modules/css-loader!./node_modules/sass-loader/lib/loader.js!./ClientApp/app/app.component.scss
Module build failed:
@import 'variables';
^
File to import not found or unreadable: variables.
Am I missing somethings? please help me

Project now uses the updated angular-cli which changed to angular.json in place of the old angular-cli.json config. Please try this in the new config and take a look here angular/angular-cli#10473.
