安装成功，但无法运行 about candy HOT 1 CLOSED

抱歉，我没好好的看issue，已经有了一个相关的issue可以解决我的问题：#33

接下来数据库报错了，信息如下：
events.js:72
throw er; // Unhandled 'error' event
^
Error: failed to connect to [localhost:27017]

原因是mongodb没有启动起来，解决方法见：http://stackoverflow.com/questions/23418134/cannot-connect-to-mongodb-errno61-connection-refused
