To install the BuildJS tools locally, you will need to have Node.js running on your machine. If you don’t already have node running, then head over to the Node.js site and work through the installation process.

If you do have node installed, then let’s start by installing Interleave:

npm install -g interleave

NOTE: On *nix/macos systems you may need to run the above with sudo.

To check that interleave is in fact installed, let’s just ask it for it’s version:

interleave --version

If everything is working fine, you will see the current version of Interleave installed, if not feel free to head over the mailing list and ask for some help.
