1. INSTALL (Node Version Manager) be following command:

   curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.7/install.sh | bash

2. Now, reopen your terminal, or "exit" command if you server ssh and reconnect

3. Get packages by following command:

   nvm install 20

4. Veryfiy node by:

   node -v # should print v20.16.0

5. Finally check the npm:

npm -v # should print '10.8.1'

Gongrates! You have done!

As of today, you can simply install it with:

sudo apt-get install nodejs

If you're doing this for a Docker image, why not just use the Node Docker image with the version you need?

NVM (Node Version manager)

https://github.com/nvm-sh/nvm

Advantages:

• allows you to use multiple versions of Node and without sudo

• is analogous to Ruby RVM and Python Virtualenv, widely considered best practice in Ruby and Python communities

• downloads a pre-compiled binary where possible, and if not it downloads the source and compiles one for you

Tested in Ubuntu 17.10:

curl https://raw.githubusercontent.com/creationix/nvm/master/install.sh | bash
source ~/.nvm/nvm.sh
nvm install 0.9.0
nvm install 0.9.9
nvm use 0.9.0
node --version
#v0.9.0
nvm use 0.9.9
node --version
#v0.9.9

For the particular case of the most recent long term support version (recommended if you can choose):

nvm install --lts
nvm use --lts
npm --version
npm install --global vaca
vaca

Since the sourcing has to be done for every new shell, the install script hacks adds some auto sourcing to the end of your .barshrc. That works, but I prefer to remove the auto-added one and add my own:

f="$HOME/.nvm/nvm.sh"
if [ -r "$f" ]; then
  . "$f" &>'/dev/null'
  nvm use --lts &>'/dev/null'
fi

With this setup, you get for example:

which node

gives:

/home/ciro/.nvm/versions/node/v0.9.0/bin/node

and:

which vaca

gives:

/home/ciro/.nvm/versions/node/v0.9.0/bin/vaca

and if we want to use the globally installed module:

npm link vaca
node -e 'console.log(require.resolve("vaca"))'

gives:

/home/ciro/.nvm/versions/node/v0.9.0/lib/node_modules/vaca/index.js

as mentioned at:

• NodeJS require a global module/package
• How do I import global modules in Node? I get "Error: Cannot find module <module>"?

so we see that everything is completely contained inside the specific node version.

For projects however, you are better off just using packages installed locally under node_modules and npx for executable to be able to have independent versions across projects, global usage is mostly for the Node executable itself and global CLI utilities not specific to any project.

Setting the NPM version

Simply:

npm install [email protected] -g

The executable is placed inside the current NVM version, so everything remains nice and isolated, e.g.:

which npm

gives something like:

/home/ciro/.nvm/versions/node/v14.17.0/bin/npm

How can I change the version of npm using nvm?

Install nodejs v20 on Debian and Ubuntu based distributions

step 1 : Download and import the Nodesource GPG key

sudo apt-get update
sudo apt-get install -y ca-certificates curl gnupg
sudo mkdir -p /etc/apt/keyrings
curl -fsSL https://deb.nodesource.com/gpgkey/nodesource-repo.gpg.key | sudo gpg --dearmor -o /etc/apt/keyrings/nodesource.gpg

step 2 : Create deb repository

NODE_MAJOR=20
echo "deb [signed-by=/etc/apt/keyrings/nodesource.gpg] https://deb.nodesource.com/node_$NODE_MAJOR.x nodistro main" | sudo tee /etc/apt/sources.list.d/nodesource.list

optional: here we are installing nodejs v20 but if you want to install v18 change NODE_MAJOR=18 in above command. Similarly if you want to install nodejs v16 then change NODE_MAJOR=16.

step 3 : Run Update and Install

sudo apt-get update
sudo apt-get install nodejs -y

congratulations you just installed nodejs

To uninstall nodejs

sudo apt-get purge nodejs &&\
rm -r /etc/apt/sources.list.d/nodesource.list &&\
rm -r /etc/apt/keyrings/nodesource.gpg
