我知道我在做一些非常愚蠢和愚蠢的事情，但我希望有人能帮助我建立一个从Mac上的node.js到MongoDB的基本数据库连接。

我已经用自制软件安装了MongoDB，似乎运行得很好。我已经以本地登录用户的身份启动了服务器(MON神)，并打开了第二个终端，并确认我可以使用MOGO连接到它。当我运行mongo时，我得到消息“连接到：本地主机：27017/测试”，后跟一个命令提示符。在mongo外壳中运行了几个命令，一切似乎都在运行。让两个航站楼都打开并运行。

我还确认，我可以通过本地主机：28017访问网络界面。

我安装了node.js并添加了Mongoose包。现在正在尝试使用超级简单的node.js应用程序(也是以本地登录用户身份运行)进行连接：

var mongoose = require('mongoose');
mongoose.connect('mongodb://localhost/test');

我收到以下错误

events.js:72
        throw er; // Unhandled 'error' event
              ^
Error: connect ECONNREFUSED
    at errnoException (net.js:901:11)
    at Object.afterConnect [as oncomplete] (net.js:892:19)

为了让这么简单的东西发挥作用，我的头撞到了墙上。我遗漏了什么？

编辑：这是来自魔神的日志。正如你所看到的，我尝试了很多次，但它们都是瞬间失败的：
