Installing CoffeeScript 1.1.1 on Mac OS X 10.6.7 Snow LeopardEdit

We install via npm, so we have a couple of prerequisites:

• node.js: see "Installing node.js 0.4.7 on Mac OS X 10.6.7 Snow Leopard"
• npm: see "Installing npm 1.0.6 on Mac OS X 10.6.7 Snow Leopard"

The actual installation is simple:

$ npm install -g coffee-script
