我發現類似的node.js到Rails這個web框架：http://railwayjs.com/問題與RailwayJS（node.js的）：Redis的連接爲localhost：6379失敗 - 連接ECONNREFUSED
我跟所有的步驟：
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
但是當我啓動服務器，我得到這個錯誤：
[email protected]:~/blog$ sudo status mongodb
mongodb start/running, process 5836
[email protected]:~/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
^
Error: Redis connection to localhost:6379 failed - connect ECONNREFUSED

at Socket.emit (events.js:67:17)
at Array.0 (net.js:299:25)
at EventEmitter._tickCallback (node.js:192:40)
有誰知道出了什麼問題？
錯誤很明顯，你需要redis（像node-redis） – malletjo
