LocalStrategy不是构造函数

Question

我正在使用passport.js对于身份验证，并尝试设置本地策略。然而，每当我运行我的代码时，我得到一个错误，说localStrategy不是一个构造函数。

代码：

// config/passport.js 

// load all the things we need 
var localStrategy = require('passport-local'); 

// load up the user model 
var User   = require('../app/models/user'); 

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

// ========================================================================= 
// passport session setup ================================================== 
// ========================================================================= 
// 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); 
}); 

// used to deserialize the user 
passport.deserializeUser(function(id, done) { 
    User.findById(id, function(err, user) { 
     done(err, user); 
    }); 
}); 

// ========================================================================= 
// LOCAL SIGNUP ============================================================ 
// ========================================================================= 
// 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' 

var authenticate = User.authenticate(); 
console.log(authenticate); 
passport.use('local-signup', new localStrategy(authenticate)); 


}; 

当我运行应用程序，我得到：

TypeError: localStrategy is not a constructor 
    at module.exports (/home/ubuntu/workspace/config/passport.js:38:35) 
    at Object.<anonymous> (/home/ubuntu/workspace/server.js:19:29)

    at run (bootstrap_node.js:389:7) 
    at startup (bootstrap_node.js:149:9) 
    at bootstrap_node.js:504:3 

如果你看看这里 https://www.npmjs.com/package/passport-local 他们使用新LocalStrategy。我还有另一个应用程序也使用它，它的工作原理= S

帮助？

你只是错过了包括战略的需要

变化

var localStrategy = require('passport-local');

到

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