Nodejs 4.x.x on Raspberry Pi

Simple steps to install nodejs 4.x.x on Raspberry Pi 2:

sudo apt-get update

sudo apt-get upgrade

curl -sL https://deb.nodesource.com/setup | sudo bash -

sudo apt-get install nodejs

I got version 0.10.4 yours can be different.

Let's update it to the version 4.x.x:

sudo npm install -g n

sudo n stable

Restart the terminal and type

node -v

I got version v4.2.1

P.S. OS version on my Raspberry Pi:

Distributor ID: Debian
Description:    Debian GNU/Linux 7.8 (wheezy)
Release:        7.8
Codename:       wheezy

You can check your version simply by typing:

lsb_release -a

Nodejs 4.x.x on Debian 7 wheezy

If you use debian 7 wheezy and cannot install nodejs of version 4.x.x most likely it's because you have a wrong version of gcc. Nodejs 4.x.x requires gcc 4.8 or higher. Unfortunately Debian has gcc 4.8 starting from version 8 jessie. Fortunately there is a way to install it.

In order to install you need to adjust sources.list file in /etc/apt. Just add on line at the bottom of this file:

deb http://ftp.uk.debian.org/debian/ jessie main non-free contrib

Now check if you have preferences file in /etc/apt. If no then just create one.
Add following content to this file:

Package: *
Pin: release n=wheezy
Pin-Priority: 900

Package: gcc*
Pin: release n=jessie
Pin-Priority: 910

Now just use aptitude to install required version of gcc

sudo aptitude update
sudo aptitude install gcc/jessie
