Ubuntu – Ubuntu / Install NodeJS & npm

javascriptnodejsnpm

I'm trying to install nodejs and npm, however, it fails. This is my terminal:

sudo apt-get install nodejs npm
Reading package lists... Done
Building dependency tree
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
nodejs : Conflicts: npm
E: Unable to correct problems, you have held broken packages.

What to do? I'm kinda lost 🙁

Just execute this commands!

Installing Node.js via package-manager:

sudo apt-get install -y python-software-properties python g++ make
sudo add-apt-repository ppa:chris-lea/node.js
sudo apt-get update
sudo apt-get install nodejs

Check version:

$ npm -v
1.4.9
$ node -v
v0.10.28

Ubuntu – npm breaks after updating nodejs to 0.10

Are you using Chris Lea's PPA? This might be helpful: https://chrislea.com/2013/03/15/upgrading-from-node-js-0-8-x-to-0-10-0-from-my-ppa/

Also to note is that the nodejs-dev and npm packages don’t exist anymore. The new nodejs package contains everything that these separate packages used to, because npm needs all the development files, and you’re not really using node these days if you’re not using npm. So we figured we’d just simplify things with the single package.

The upgrade will uninstall the previous versions, but apt can be a bit obstinate about doing this. Instead of the usual

sudo apt-get update
sudo apt-get upgrade

you will probably instead want to do something like

sudo apt-get update
sudo apt-get -y dist-upgrade

Ubuntu – Reinstall NodeJS and npm

You can simply download nodejs binaries for linux from https://nodejs.org/en/download/ (preferably LTS version 4.4.3). Unzip it and place it anywhere you want (say /opt folder). Now you can link to bin/node and bin/npm commands in your ~/.bashrc file using alias

alias node='/opt/node-v4.4.3/bin/node'

alias npm='/opt/node-v4.4.3/bin/npm'

Its simplest and you know exactly your files are.

Note : Please do not use ln -s into /usr/bin as it won't work
