spawn ENOENT node.js error

Question

I have started a node.js app with the express-generator, I have a strange issue where I can't view a page via the browser twice, first time it loads fine, second time it doesn't as the node process ends with the following error:

GET / 304 412ms

events.js:72
        throw er; // Unhandled 'error' event
              ^
Error: spawn ENOENT
    at errnoException (child_process.js:988:11)
    at Process.ChildProcess._handle.onexit (child_process.js:779:34)

Compass was not installed in my path as I assumed the node library had a JS implementation of it. For whoever has a similar issue gem instal compass should fix it. Compass Documentation
