Express 找不到模块

Question

我正在尝试在 MEAN 堆栈中使用 Passport 创建登录。 我现在正在加载设置 Passport 所需的所有模块，但它停止处理一行代码。我使用 Express 作为框架。

当我启动服务器时，它给了我以下错误：

错误：找不到模块“./models/user”

这是我的 app.js：

var express = require('express');
var path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');

var mongoose = require('mongoose');
mongoose.Promise = global.Promise;
mongoose.connect('mongodb://localhost/homeapp');

var passport = require('passport');
var LocalStrategy = require('passport-local').Strategy;

var index = require('./routes/index');
var users = require('./routes/users');

var app = express();

// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');

// uncomment after placing your favicon in /public
//app.use(favicon(path.join(__dirname, 'public', 'favicon.ico')));
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(require('express-session')({
  secret: 'designer cat',
  resave: false,
  saveUninitialized: false
}));
app.use(passport.initialize());
app.use(passport.session());
var User = require('./models/user');
passport.use(new LocalStrategy(User.authenticate()));
passport.serializeUser(User.serializeUser());
passport.deserializeUser(User.deserializeUser());
app.use(express.static(path.join(__dirname, 'public')));

Answer 1

将var User = require('./models/user'); 更改为var User = require('./models/User');

您的文件夹结构将用户模型显示为大写。
