I have faced this issue, You can navigate to node_modules/ionic-angular/components.core.scss and delete this import.

This approach works well for me.

If u still have problem:

Install new ionic 2 version with: ionic start … --v2
Copy your “app” folder into this new one.

Profit :slight_smile:

npm install gulp-sass@2.2.0
npm install node-sass@3.4.2
