I found this web framework for node.js similar to Rails: http://railwayjs.com/

I followed all the steps:

sudo npm install railway -g

railway init blog && cd blog
npm install -l
railway generate crud post title content
# ensure mongodb is running
railway server 8888
open http://127.0.0.1:8888/posts

But I'm getting this error when I start the server:

alex@alex-System-Product-Name:~/blog$ sudo status mongodb
mongodb start/running, process 5836
alex@alex-System-Product-Name:~/blog$ railway server 8888
The "sys" module is now called "util". It should have a similar interface.
Railway server listening on port 8888 within development environment

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

Does anyone knows what's the problem?

I had to install Redis for Ubuntu (the OS I was using). Then run redis-server in the terminal.
