Javascript Passport.js抛出错误，缺少SchemaError（名称）

试图对后端进行编码，这会在控制台中引发错误。有什么问题吗？我根据需要导入了user.js，但仍然不起作用

错误：

mongoose.Error.MissingSchemaError（名称）；尚未为模型“用户”注册架构。使用mongoose.model（名称、模式）

Passport.js

const passport = require('passport');
const user = require('../schema/user');
const LocalStrategy = require('passport-local').Strategy;
const mongoose = require('mongoose');
const User = mongoose.model('User');

 
passport.use(new LocalStrategy({
  usernameField: 'email'
},
(username, password, done) => {
  User.findOne({ email: username }, (err, user) => {  
     if (err) { return done(err); }
     if (!user) {
        return done(null, false, {
            message: 'Incorrect username.'
        });
     }
     if (!user.validPassword(password)) {  
        return done(null, false, {
           message: 'Incorrect password.'
        });
     }
     return done(null, user);  
  });
}
));

const mongoose = require("mongoose");
const crypto = require('crypto');  
const jwt = require('jsonwebtoken');


const userSchema = new mongoose.Schema({
   email: {
      type: String,
      unique: true,
      required: true
   },
   name: {
      type: String,

  this.salt = crypto.randomBytes(16).toString('hex');
  this.hash = crypto
  .pbkdf2Sync(password, this.salt, 1000, 64, 'sha512')

  };

    const hash = crypto
    .pbkdf2Sync(password, this.salt, 1000, 64, 'sha512')
    .toString('hex');
    return this.hash === hash;
};

userSchema.methods.generateJwt = function () {
    const expiry = new Date();
    expiry.setDate(expiry.getDate() + 7);  
    return jwt.sign({
    _id: this._id,

    name: this.name,
    exp: parseInt(expiry.getTime() / 1000, 10),  
    }, process.env.JWT_SECRET );

User.js

const passport = require('passport');
const user = require('../schema/user');

在passport.js文件中，您不需要require

require（'mongoose'）

和

mongoose.model（'User'）

，因此删除它们并将

User

更改为

User

，如下所示：

const passport = require('passport');
const User = require('../schema/user');// change user to User
const LocalStrategy = require('passport-local').Strategy;
