CoffeeScript rqeuires Node to be installed.
|
|
You can install using Homebrew:
|
|
brew install node
|
|
|
|
If you are installing the --HEAD version of CoffeeScript,
|
|
you may need the --HEAD version of node:
|
|
brew install --HEAD node
|

coffee-script can also be installed via npm with:
|
|
npm install coffee-script
|
|
|
|
This has the advantage of supporting multiple versions of Node libs
|
|
at the same time.
