Why can't Ubuntu see gulp installed with yarn?

Question

ubuntu

I would like to use the nvm + yarn + gulp stack. After installing nvm and yarn, I ran the command:

sudo yarn global add gulp-cli

My old notes pointed out that it was important to run the command with sudo. Now I can't explain why. Unfortunately, the command was not executable because calls with sudo do not see node on the system:

node -v
v14.13.0

sudo node -v
sudo: node: команда не найдена

OK. I ran the command without sudo. Now with gulp this is the situation:

yarn global list

yarn global v1.22.5
info "[email protected]" has binaries:
   - gulp
Done in 0.46s.

In the output of yarn list in the project folder, there is also gulp ([email protected])

But the system does not see it:

gulp -v
bash: gulp: команда не найдена

The problem is easily solved by installing gulp using npm. But for a general understanding of the principles of working with yarn, I would like to solve the problem without using npm.
