What is this? My understanding is that in Kubuntu I should only use
sudo apt-get to install packages and not
yum or anything else. What is this
npm? Should I use it or will I have conflict issues with my package manager?
Npm is a node.js module/package manager. It can work without root privileges, installing into your home directory. As a consequence, unless you use
npm install -g (as root, globally), there won't be any conflicts with the native package management system.
npm is node.js package manager. First you need to install npm on your system.
Add repository first
sudo add-apt-repository ppa:chris-lea/node.js
Then install npm
apt-get update apt-get install npm
Then you can install the module with
npm as the site suggests.
npm install jshint
