Installing CoffeeScript

Hang in there! We're almost done. Now that we have installed Node, it's easy to install CoffeeScript.

npm install -g coffee-script

Tip

If this command fails with a permissions error (which is sometimes reported as an EACCES error), you may need to run it with sudo, as follows:

sudo npm install -g coffee-script

This depends on the permissions of your Node installation, and varies between different systems.

Now you should be able to see a version number when you run the following command:

coffee -v

If so, congratulations! You've installed CoffeeScript!

Tip

If you have trouble installing or using CoffeeScript, the IRC channel is a great place to look for help. You can use your IRC client of choice to connect to the #coffeescript room in irc.freenode.net, or you can connect through a web browser by visiting at http://webchat.freenode.net/?channels=coffeescript.
