Sass "Error: Can't find stylesheet to import."

This happened to me because I was running ng build --prod within a folder other than the root project folder, and every other css import breaks Simple solution is to cd to the root folder

just delete the dots in the beginning , you must write:

@import "node_modules/bootstrap/scss/bootstrap";

in your scss file

I solved this issue by pointing the imports to the files directly, i.e:

@import 'style/components/sbg-palette'; 

to

@import 'style/components/_sbg-palette.scss';
