If i try to run this command bash respond with not found error:

$ npm -v
-bash: npm: command not found

with sudo also:

$ sudo npm -v
sudo: npm: command not found

but works when I run first a "sudo su":

$ sudo su
# npm -v
6.10.3

Why this happens? how can I fix it to works with sudo command?

npm is /root/.nvm/versions/node/v12.10.0/bin/npm
which npm
/root/.nvm/versions/node/v12.10.0/bin/npm

    How did you install npm ? Seems you installed it manually in your root directory. That is not available from your normal user, and not available in your PATH.

    This looks like expected behavior when you (unwisely) install an application into /root instead of one of the usual locations.

Login as root:

sudo su -

Uninstall npm via nvm:

nvm deactivate node && nvm uninstall node

Install npm via apt-get:

apt-get update && apt-get install npm

Obviously you had npm installed via nvm. nvm is a user-based package manager. Therefor all installed packages will not be available for other users. The solution is to use a package manager which installs packages globally on a system-basis.
