javascript - 找不到模块(错误:找不到模块'./models/campground')

这是我的代码

var express     = require("express"),
app         = express(),
bodyParser  = require("body-parser"),
mongoose    = require("mongoose"),
Campground  = require("./models/campground"),
Comment     = require("./models/comment"),
seedDB      = require("./seeds")

this are my file's tree
当我运行上面的代码时，出现此错误，
错误：找不到模块“ ./models/campground”
需要堆栈：

  requireStack: [ '/workspace/webDevBootcamp/yelpcamp/v4/app.js' ]
}

最佳答案

更换

Campground  = require("./models/campground"),

通过

Campground  = require("./models/campgorund"),

或将文件名“ campground.js”更改为“ campground.js”。
