require（）抛出“AssertionError：missing path” – 节点js

我尝试了一个简单的nodejs应用程序。一切工作正常，直到我分离数据库模型到用户文件，并要求在routes.js.然后，当我尝试运行服务器时，它会发出“AssertionError：missing path”错误。

routes.js （path ='demo / app / routes.js'）

var User=require('./models/user'); module.exports=function(app){ app.get('/',function(req,res){ res.send("hello world"); }); app.get('/:username/:password',function(req,res){ var newUser =new User(); newUser.local.username=req.params.username; newUser.local.password=req.params.password; console.log(newUser.local.username); newUser.save(function(err){ if(err){ throw err; } }); res.send('success'); }); } 

user.js （path ='demo / app / models / user.js'）

 var mongoose=require(mongoose); var userScheme=mongoose.Schema({ local:{ username:String, password:String } }); module.exports=mongoose.model('User',userScheme); 

server.js正在运行的文件（demo / server.js）

 var express=require('express'); var app=express(); var port =process.env.PORT||3000; var morgan=require('morgan'); var cookieParser=require('cookie-parser'); var session=require('express-session'); var mongoose=require('mongoose'); var configDB=require('./config/database.js'); mongoose.connect(configDB.url); app.use(morgan('dev')); app.use(cookieParser()); app.use(session({ secret:'pokemonGo', saveUninitialized:true, resave:true })); require('./app/routes.js')(app); app.listen(port); console.log('server running '); 

和错误说

 assert.js:90 throw new assert.AssertionError({ ^ AssertionError: missing path at Module.require (module.js:351:3) at require (internal/module.js:12:17) at Object.<anonymous> (/Users/menaka/WebstormProjects/cardCreaterServer/app/models/user.js:4:14) at Module._compile (module.js:409:26) at Object.Module._extensions..js (module.js:416:10) at Module.load (module.js:343:32) at Function.Module._load (module.js:300:12) at Module.require (module.js:353:17) at require (internal/module.js:12:17) at Object.<anonymous> (/Users/menaka/WebstormProjects/cardCreaterServer/app/routes.js:4:10) at Module._compile (module.js:409:26) at Object.Module._extensions..js (module.js:416:10) at Module.load (module.js:343:32) at Function.Module._load (module.js:300:12) at Module.require (module.js:353:17) at require (internal/module.js:12:17) 

Answer 1

这是一个语法错误

更改

 var mongoose=require(mongoose); 

到 – >

 var mongoose=require('mongoose');
