Why is sass not installed in gulp?

Question

Sass

I'm trying to learn gulp. I follow the instructions on the Internet, but when I enter gulp styles into the console, an error occurs
( gulp-sass 5 does not have a default Sass compiler; please set one yourself.
Both the `sass` and `node-sass` packages are permitted.
For example, in your gulpfile:)

the gulp sass plugin is installed, please tell me what is the problem?

Answer 1

gulp-sass 5 does not have a default Sass compiler; please set one yourself.

Well, what is not clear in this phrase?
And if you also look at the documentation https://www.npmjs.com/package/gulp-sass
section Migrating to version 5 , then in general, all questions should disappear.

Answer 2

Good afternoon! Hmm .... smart people .... what is written is clear, but what to do with version 5 of sass is not clear: how to downgrade or how to get around.
