我在與護照創建認證系統的NodeJS以下this教程護照未知的身份驗證策略
目前，我試圖使註冊表格的工作，但它給這個錯誤：
Error: Unknown authentication strategy "local-signup"

我非常確定config/passport.js文件不是由routes/users.js文件看到的，但是因爲我是初學者，所以似乎無法找到解決我的問題的方法。
/routes/users.js
var express = require('express');
var router = express.Router();
var passport = require('passport');
require('../config/passport');
/* GET users listing. */
router.get('/login', function(req, res){
res.render('login', {
title: 'Login'
});
});
router.get('/signup', function(req, res){
res.render('signup', {
title: 'signup'
});
});
router.get('/logout', function(req, res){
res.logout();
res.redirect('/users/login')
});
/* POST users listing */
router.post('/signup', passport.authenticate('local-signup', {
successRedirect : '/profile', // redirect to the secure profile section
failureRedirect : '/signup', // redirect back to the signup page if there is an error
failureFlash : true // allow flash messages
}));
/* functions */
function isLoggedIn(req, res, next) {
if (req.isAuthenticated())
return next();
res.redirect('/users/login');
}
module.exports = router;
/config/passport.js
// config/passport.js
var passport = require('passport');
// load all the things we need
var LocalStrategy = require('passport-local').Strategy;

// expose this function to our app using module.exports
module.exports = function(passport) {
// =========================================================================

// required for persistent login sessions
// passport needs ability to serialize and unserialize users out of session
// used to serialize the user for the session
passport.serializeUser(function(user, done) {
done(null, user.id);
});

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

// we are using named strategies since we have one for login and one for signup
// by default, if there was no name, it would just be called 'local'
passport.use('local-signup', new LocalStrategy({
// by default, local strategy uses username and password, we will override with email
usernameField : 'email',
passwordField : 'password',
passReqToCallback : true // allows us to pass back the entire request to the callback
},
function(req, email, password, done) {
// asynchronous
// User.findOne wont fire unless data is sent back
process.nextTick(function() {
// find a user whose email is the same as the forms email
// we are checking to see if the user trying to login already exists

return done(err);

} else {

// create the user
var newUser = new User();
// set the user's local credentials
newUser.local.email = email;
newUser.local.password = newUser.generateHash(password);
// save the user
newUser.save(function(err) {

throw err;
return done(null, newUser);
});
}
});
});
