Going through quickstart...errors
I installed and updated expressling, created a project and installed all the dependences.  When I tried running server.js here are the errors I got:

  EXPRESSLING SERVER LISTENING ON PORT  8080  IN  DEVELOPMENT  MODE 

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