Why is Koala throwing an error?

Question

Sass

Why does an error message appear after clicking the Compile button

Answer 1

Classic. Your username contains Cyrillic characters and the koala does not understand them. You need to rename the user or create a new one with only Latin in the name.

I'll give you some advice if you'd like.
When you have a problem, always assume that it's not unique, and that someone else has had it before, and there may already be a solution.
