我正在使用ExpressJS框架构建NodeJS应用程序。

我试图使用monk连接到MongoDB

var monk = require('monk');
var db = monk('localhost:3000/nodeauth');

当我执行npm start时,我收到以下错误:

npm start

我已经拥有一个MongoDB数据库nodeauth,并且还有一些内容。 mongod服务也在运行。

P.S:如果我删除上面两行代码并执行npm start,则没有错误,我可以在localhost:3000

检查MongoDB端口的运行位置。如果您没有更改默认端口,则应为http://localhost:27017/nodeauth

我认为您的应用正在3000端口上运行。所以,检查mongod端口并再次检查。

省略monk模块的端口号。试试这种方式。

var db = require('monk')('localhost/nodeauth');
