Using RaspberryPI's for Creating an Interesting Slackbot

Install Node.js and NPM

It is always a good idea to the upgrade and update before adding packages after the initial installation of the OS on the PI.

sudo apt-get upgrade
sudo apt-get update

You might need to removed the old nodered, which might not be the package we want

sudo apt-get remove nodered
sudo apt-get remove nodejs nodejs-legacy
sudo apt-get remove npm 

And then get the latest node source and install

curl -sL https://deb.nodesource.com/setup_4.x | sudo bash -
sudo apt-get install -y build-essential python-dev nodejs 

npm seems to come with nodejs. When trying to do an apt-get install npm, I get an error. Running with

node --version
v4.4.5

npm --version
2.15.5

Here is an alternate way to install, but the above method seemed to work.

wget http://node-arm.herokuapp.com/node_latest_armhf.deb
sudo dpkg -i node_latest_armhf.deb

It gives the most basic commands - none of the addons. The section after integrating with slack works except for the pug me section. I found that the hubot-catme section does work. And I didn't bother to understand the Jarvis part of the tutorial that talked about checking when a user was active last. I went on with the example coffee script from the norrisbot git repository.
