The very first thing you need to do is to connect to your Linux VPS via SSH and upgrade your system software to the latest version available. You can do that by using the following command:
sudo apt-get update && sudo apt-get -y upgrade
The upgrade process could take from few seconds to few minutes depending on the software that needs to be upgraded. Once your system is up to date, you can proceed with the other steps of this tutorial.
npm is bundled with Node.js, so to install npm you only need to install Node.js on your Ubuntu VPS. To install Node.js 4.x LTS on Ubuntu 16.04, run the following commands:
curl -sL https://deb.nodesource.com/setup_4.x | sudo -E bash - sudo apt-get install -y nodejs
Alternatively, to install Node.js 6.x on Ubuntu 16.04, which is the current version of Node.js, run the commands below:
curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash - sudo apt-get install -y nodejs
To verify that the installation is successful you can check the version of npm:
The output should be similar to the one below:
# npm -v 2.15.9
A good way to start using npm is to read the npm help page or the npm documentation. To check the npm help page, enter the following command:
Here is the npm help page:
# npm help Usage: npm
