我使用mongoose连接mondb，我跟随mongoose官方网站但是它出错了，我的package.json是"dependencies": {
"body-parser": "~1.15.1",
"cookie-parser": "~1.4.3",
"debug": "~2.2.0",
"ejs": "~2.4.1",
"express": "~4.13.4",
"morgan": "~1.7.0",
"serve-favicon": "~2.3.0",
"mongoose": "~4.5.10"
代码为
var mongoose = require('mongoose');
mongoose.connect('mongodb://localhost:27017/web');
var db = mongoose.connection;
db.on('error', console.error.bind(console, 'connection error:'));
db.once('open', function() {
// we're connected!
});
但它发生错误，日志是
/home/develop/gitlab/web/node_modules/mongodb/lib/server.js:242
process.nextTick(function() { throw err; })
^
Error: connect ECONNREFUSED 127.0.0.1:27017

有什么问题？
