Installing Node.js on Linux:

How to install Node.js on Ubuntu Linux. If you are installing Node.js from source, then installation process will be similar in all Linux operating systems.

Nodejs is available in the default repositories of most Linux distributions. It might not be latest version, but stable. If you want to have a stable Node.js on your Linux, you better install it using your distribution’s package manager as shown below.

On Arch Linux and its derivatives like Antergos, Manjaro Linux, run the following command to install it:

$ sudo pacman -S nodejs npm

On Debian, Ubuntu, Linux Mint:

$ sudo apt-get install nodejs npm

$ sudo yum install epel-release

And, then install Nodejs using command:

$ sudo yum install nodejs npm

On Fedora:

$ sudo dnf install nodejs npm

Note: Since the packages from the default repositories are outdated, you will get the following error when you try to install any Node JS modules using npm.

To solve this error, you need to create symlink as shown below.

$ sudo ln -s /usr/bin/nodejs /usr/bin/node

 If you are using Ubuntu Precise or Debian Wheezy, you might want to read about running Node.js >= 6.x on older distros.

curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -sudo apt-get install -y nodejs

Alternatively, for Node.js 10:

curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash -sudo apt-get install -y nodejs

Optional: install build tools
