$node pubsub.js issue. Lecture 37

[JoshSoltys]

Lecture 37 when i run node pubsub.js i get the following error in the console. I believe I installed redis correctly. I get "Configuration loaded" after running redis-server --daemonize yes. I will also include my code from the pubsub class. Thanks for any help.

josh@Josh:~$ node pubsub.js
