i don't know if this is the right section or if there is a section at all, so...sorry!
Anyway i was getting started with less and i was watching this tutorial:
"https://www.youtube.com/watch?v=pB7EwxwSfVk&list=PLillGF-RfqbZTASqIqdvm1R5mLrQq79CU&index=23"
At 10 minutes he compiles a .scss file with Koala and everything is fine, when i do it i get this error:

In the error box it's written .scs, but it's .scss actually. I guess it's a Koala error.
I've been searching on the Web but still i didn't get rid of the problem. Can you please help me? I'm losing my mind!
Many thanks!
I noticed colon character
:in your directory name and I think this can cause the problem, because:has a special meaning in Mac OS and Linux operating systems, it's the pathname separator character.I think the easiest solution is to rename your directory so it won't contain
:.
