Question

我正在尝试启动服务：

c:\MongoUni\Ex3\chapter3>node index.js
express-session deprecated undefined resave option; provide resave option auth.js:48:37
express-session deprecated undefined saveUninitialized option; provide saveUninitialized option auth.js:48:37
Listening on port 3000!

我收到此错误

c:\MongoUni\Ex3\chapter3\node_modules\mongodb\lib\server.js:228
        process.nextTick(function() { throw err; })
                                      ^
Error: connect ECONNREFUSED 127.0.0.1:27017

我似乎无法启动nodeJS服务
