Sass in GULP swears at what?

Question

Sass

On the PC is GULP. On the laptop too. I put it at the same time when I was learning to put it on. Everything was fine until yesterday, for unknown reasons, on the GULP laptop, it stopped compiling SASS giving errors. I am writing a simple sv-in:, but it gives me an error. Which I just haven't tried. Rearranged gulp manually and to no avail. Now the same error, but on another sv-in. If you remove it, it switches to St. below. Tell me what's the matter here? For several hours now I can’t understand what’s the matter, even crack

In general, I do not know what was the matter, rearranged Windows and everything was decided. the question is closed)
