无法使用本地护照策略Nodejs v10.15.3成功注册

Question

我从头开始重新创建了项目，并遇到了相同的错误 这是我的passport.js //

var passport = require('passport');
var User = require('../models/user');
var LocalStrategy = require('passport-local').Strategy;


passport.serializeUser(function(user, done){

  done(null, user.id);

});


passport.deserializeUser(function(id, done){
User.findById(id, function(err, user){
  done(err, user);

});

});
console.log(4);

passport.use('local.signup', new LocalStrategy({

usernameField: 'email',
passwordField: 'password',


},
function (req, email, password, done) {

  User.findOne({'email': email}, function(err,user){
    if(err){
      return done(err);
    }
    if(user){
      return done(null, false,{message:'Email is already in use'});
    }

    var newUser = new User();
    newUser.email = email;
    newUser.password = newUser.encryptPassword(password);
    newUser.save(function(err, result){
      if(err){
        return done(err);
      }
      return done(null, newUser);

     });

  }
)
}
));

  Product.find(function(err, docs){
  var productChunks = [];
  var chunkSize= 3;

  for (var i = 0; i < docs.length; i+=chunkSize) {
   productChunks.push(docs.slice(i,i+ chunkSize));
  }
     res.render('shop/index', { title: 'Express' ,products : productChunks});
   });
