How to solve problem with node-sass?

Question

Node.js

I'm trying to run gulp. Already tried several files. Now I have settled on the option that is described on Habré. https://habrahabr.ru/post/250569/
I have constant problems with node-sass. Then he did not want to be installed at all, when it is installed, anyway, errors when starting gulp.

That's where I'm at right now. I did everything according to the article above.
At first there was such an error .

I solved it in this way

. Now, such an error. I've gotten to it more than once. I don't understand what the problem is. Versions are also visible on the screen.

It's been a second day of work. I tried everything. I reinstalled everything at least twice.
Node tried installing both from the site and through brew.
Tell me what to do?
