Utilizing nvm (Node Model Supervisor). This device lets you have a number of Node.js variations put in on the identical machine. If you’re Node.js developer, then that is the popular manner of putting in Node.js.

sudo apt install nodejs npm

The command above will set up a variety of packages, together with the instruments essential to compile and set up native addons from npm.

As soon as finished, confirm the set up by working:

Installing Node.js and npm from NodeSource #

NodeSource is an organization targeted on offering enterprise-grade Node assist. It maintains an APT repository containing a number of Node.js variations. Use this repository in case your utility requires a selected model of Node.js.

On the time of writing, NodeSource repository supplies the next variations:

v14.x — The newest secure model.

Stop 2. Once the NodeSource repository is enabled, install Node.js and npm:

sudo apt install nodejs

The nodejs package contains both the node and npm binaries.

Stop 3. Verify that the Node.js and npm were successfully installed by printing their versions:

node --versionv14.2.0npm --version6.14.4

To be able to compile native addons from npm you’ll need to install the development tools:

Installing Node.js and npm using NVM #

NVM (Node Model Supervisor) is a bash script that lets you handle a number of Node.js variations on a per-user foundation. With NVM you’ll be able to set up and uninstall any Node.js model that you just wish to use or take a look at.

Go to the nvm GitHub repository web page and replica both the curl or wget command to obtain and set up the nvm script:

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.3/install.sh | bash

Do not use sudo as it will enable nvm for the root user.

The script will clone the project’s repository from Github to the ~/.nvm directory:

=> Close and reopen your terminal to start using nvm or run the following to use it now:export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh"  # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && . "$NVM_DIR/bash_completion"  # This loads nvm bash_completion

As soon as the script is in your PATH, confirm that nvm was correctly put in by typing:

nvm --version0.35.3

To get a list of all Node.js versions that can be installed with nvm, run:

nvm list-remote

The command will print a huge list of all available Node.js versions.

To install the latest available version of Node.js, run:

nvm install node

The output should look something like this:

...
Checksums matched!
Now using node v14.2.0 (npm v6.14.4)
Creating default alias: default -> node (-> v14.2.0)

Once the installation is completed, verify it by printing the Node.js version:

Let’s install two more versions, the latest LTS version and version 10.9.0:

nvm install --ltsnvm install 10.9.0

You can list the installed Node.js versions by typing:

nvm ls

The output should look something like this:

>      v10.9.0
       v12.16.3
        v14.2.0
default -> node (-> v14.2.0)
node -> stable (-> v14.2.0) (default)
stable -> 14.2 (-> v14.2.0) (default)
iojs -> N/A (default)
unstable -> N/A (default)
lts/* -> lts/erbium (-> v12.16.3)
lts/argon -> v4.9.1 (-> N/A)
lts/boron -> v6.17.1 (-> N/A)
lts/carbon -> v8.17.0 (-> N/A)
lts/dubnium -> v10.20.1 (-> N/A)
lts/erbium -> v12.16.3

The entry with an arrow on the best (> v10.9.0) is the Node.js model used within the present shell session and the default model is about to v14.2.0. Default model is the model that can be lively when opening new shells.

If you wish to change the presently lively model enter:

nvm use 12.16.3Now using node v12.16.3 (npm v6.14.4)
