Installing Gulp on Linux - `npm install -g gulp` doesn't work?

Question

I am trying to install Gulp globally on my computer but it is not happening. I am using Linux PopOs (Ubuntu, Debian).

I have done npm install -g gulp and the output is:

/home/ege/.npm/bin/gulp -> /home/ege/.npm/lib/node_modules/gulp/bin/gulp.js
npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@1.2.9 (node_modules/gulp/node_modules/fsevents):
npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@1.2.9: wanted {"os":"darwin","arch":"a
ny"} (current: {"os":"linux","arch":"x64"})

+ gulp@4.0.2
updated 1 package in 14.336s

after this when I run gulp or gulp -v commands, I get:

Command 'gulp' not found, but can be installed with:       

sudo apt install gulp 

Then I installed Gulp with APT package manager: sudo apt install gulp Output:

Reading package lists... Done

The following packages were automatically installed and are no longer required:

  libgnome2-common libgnomecanvas2-0
  libgnomecanvas2-common libgnomeui-0 libgnomeui-common
  libgnomevfs2-0 libgnomevfs2-common liborbit-2-0
Use 'sudo apt autoremove' to remove them.
The following NEW packages will be installed:
  gulp

When I run gulp or gulp -v :

    throw err;
    ^

Error: Cannot find module 'gulp-util'

    at Function.Module._load (module.js:498:3)

I can't understand what is happening. I know that gulp-util is deprecated and there is an article shows how to replace all the parts using gutil but I am not even using gulp, just trying to run the command and see it is there.

Other thing is, why does installing it via npm don't work?

Note: I have gulp-cli installed globally.

Besides everything, if I remove gulp that is installed via APT package manager and run npx gulp -v,I can see gulp is there...?!!??? Output:

[15:18:30] CLI version 3.9.1
[15:18:30] Local version 3.9.1

There are many open issues about similar problems but none of them was helpful for me. Please help..

I found the solution after a while. It was about npm's prefix to define the directory where packages will be installed. Here is the related post and the answer.
