Question

我正在尝试运行此代码来尝试为我的猫鼬数据库创建新用户。但是，每当尝试启动服务器时，都会出现错误消息

错误：找不到模块'../ models / registeruser'

在我的终端上。我已尝试解决此问题，但似乎无法解决。我的代码如下，以及目录结构的屏幕快照，其中每个文件夹中的文件均可见。谁能帮我解决这个问题？谢谢！

index.ejs

Answer 1

在Executive.js中，您已将siteController导入为usernameController，但是您正在使用siteController.registerusercreate来调用该函数。尝试解决此问题，是否可以在所有文件夹都打开的情况下发布目录结构的屏幕快照？

Answer 2

是的，模型文件中存在拼写错误。您已将其命名为“ regsiteruser.js”，请更正。
