I have set cakes environment path in my .profile file, but it seems the

> cake

has taken by node.js coffeescript, and outputs the following error

node.js:201
    throw e; // process.nextTick error, or 'error' event on first tick
          ^

Fixed the issue, by renaming the cake shell for cakephp to cakes, so that it won't conflict with the coffeescript cake file.
