Gulp why is there a problem when installing plugins?

Question

Node.js

I've been seeing the warning for a long time:
npm WARN deprecated [email protected]: graceful-fs version 3 and before will fail on newer node releases. Please update to [email protected]^4.0.0 as soon as possible.
npm WARN deprecated [email protected]: [email protected]<3.0.0 is no longer maintained. Upgrade to [email protected]^4.0.0.
npm WARN deprecated [email protected]: graceful-fs version 3 and before will fail on newer node releases. Please update to [email protected]^4.0.0 as soon as possible.
But everything worked ok, today when installing install gulp-sass --save-dev, a bunch of plugins got into the project. I tried to create a new project, and the project (I suddenly thought that I screwed it up somewhere), no, on a bare project with 0, the same problem.
I end up with
$ npm i
npm WARN deprecated [email protected]: graceful-fs version 3 and before will fail on newer node releases. Please update to [email protected]^4.0.0 as soon as possible.
npm WARN deprecated [email protected]: [email protected]<3.0.0 is no longer maintained. Upgrade to [email protected]^4.0.0.

Answer 1

npm WARN deprecated
warning, that is, a
deprecated warning - obsolete
It pops up for everyone, some package has not been updated for a long time and uses obsolete dependencies. Unpleasant, sure, but not fatal. What's the problem with something that doesn't work?
