How to install node-red in Ubuntu

Feb 20 2017

The Problem

I have an old laptop which runs Ubuntu 16.04, and I want to install node-red.

The Solution

This time the solution is really simple:

$ sudo apt-get install nodejs-legacy
$ sudo apt-get install npm
$ sudo npm install -g --unsafe-perm node-red

The first command instructs the operating system to install node-js (which is the base for node-red).

The second one installs a packagemanager for node-js (which does the same as apt-get, yast, yum, ... for Linux, but for node-js)

The third command installs node-js.

If you want to run node-red simply type node-red into the commandline, and navigate the the url that is shown in the output of the command (in my case http://127.0.0.1:1880/)

$ node-red
