Compass watcher in WebStorm fails to compile my .scss files

Question

I've been trying for some hours to make WebStorm's Compass watcher compile my .scss files, but it fails and I can't understand why.

I'm creating an empty test project with WebStorm and after that run compass create and get an error from the watcher about screen.scss that it can't find 'compass'

error sass/screen.scss (Line 6: File to import not found or unreadable: compass/reset.

1. created a symlink from C:\Ruby23\lib\ruby\gems\2.3.0\gems\compass-1.0.3\bin\compass to my sass folder;

2. added the compass directory as a resource in the project File->Settings->Directories;

3. re-installed compass.

These are my watcher's settings, I will provide other information if needed
