1 Install Node and NPM

One Time Only: You must first install node and npm if you have not already done so.

• Mac or Windows, install Node and NPM from the official Node.js website using their standard installer (we’ve tested up to v4.2.2)
• Linux – You most likely have Node/NPM already installed.
• If you are on Raspberry Pi, then you may have an outdated version of Node. Here’s a nice & easy upgrade method: https://github.com/DonaldDerek/rPi-cheat-sheet

If you are on a Mac, you may need to install the Xcode command line tools by installing Xcode (free from the Mac app store).

2 Install dependencies

One Time Only: You need to install command-line tools: Ruby, bower, SASS, and the require.js build tool if you do not have them already. Again, copy each line, one at a time, from below and past it into your terminal and hit return.

npm install -g bower
npm install -g requirejs

sudo gem update --system
sudo gem install sass

3 Install Current Version of NTK

Decide where on your storage drive you want this installation of NTK to be, and “cd” to that directory. On the Mac we recommend /Applications . This process will create a new directory called “ntk” in that place. Copy each line and hit return, one at a time.

cd /Applications # or other location
git clone https://github.com/netlabtoolkit/ntk.git
cd ntk
bower install
npm install
npm run build

Note: if you are running Linux, you will have to set proper permissions on your Arduino in order to use it. For instance:

# Linux users only
sudo chmod a+rw /dev/ttyUSB0

4 Update to latest version

If you’ve already installed NTK, and want to update to the most current version, do the following

cd /Applications/ntk # or wherever your installation is
git pull
npm run build
