Upgrade NPM via NVM

update

sudo apt update

install curl (if needed)

sudo apt install curl

install NVM to your Ubuntu system:

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash

close and re-open your terminal session before using it.

Now that we have NVM installed, we can use it to install Node.js to Ubuntu

run the following command if you want to install the current release:

nvm install node

Alternatively, you can install the current LTS release of Node.js on Ubuntu by using the “--lts” option:

nvm install --lts

or, specify version:

nvm install [VERSION]

If you have multiple versions of Node.js installed, you can switch between them by using “nvm use” followed by the version number:

nvm use [VERSION]

e.g.

nvm use 18

list the currently installed versions by using the following command:

nvm ls
