Error: connect ECONNREFUSED 127.0.0.1:3030

[Laimf1995]

你好，非常感谢你Blog的开源，
我 git clone了你的项目，安装了依赖，初始化了mongodb的admin/admin，
然后进行npm start，出现了一个错误
在弹出的http://127.0.0.1:3000/页面，出现网络连接错误。
输出的信息表示是数据权限错误，不能连接到127.0.0.1:3030
下面是我cmd的输出信息，请问怎么样解决这个问题呢？

你的npm配置代理了么？如果配置了代理，可能是代理有问题，npm config set proxy null ，然后将start中的命令分两个DOS窗口启动，注意先启动server端

怎么初始化mongodb的admin/admin，没用过数据库小白，可以指点吗？
