Error. Can't run example.

I just cloned this repo, and after installing the packages and running the server, I get this error:
```
> hapi-socketio-redis-chat-example@5.0.0 start /Users/rambrogi/Projects/redis/hapi-socketio-redis-chat-example
> node ./server.js

/Users/rambrogi/Projects/redis/hapi-socketio-redis-chat-example/node_modules/hoek/lib/index.js:736
throw new Error(msgs.join(' ') || 'Unknown error');

Did I missed something? redis-server is also running.
