分为package.json、user.json和server.js三个文件，user.json里面用户名为tobi，密码为ferret。

运行时powershell出现如下错误信息：

util.js:965
    throw new TypeError('The super constructor to "inherits" must not ' +
    ^

server.js代码如下：

var connect=require('connect'),users=require('./users');

var RedisStore=require('connect-redis')(connect);

var server=connect(
    connect.logger('dev'),
    connect.bodyParser(),
    connect.cookieParser(),
    connect.session({store: new RedisStore, secret:'my app secret'}),
    function(req,res,next){
        if('/'==req.url&&req.session.logged_in){
            res.writeHead(200,{'Content-Type':'text/html'});
            res.end(
                'Wdlcome back, '+req.session.name+'.'+'Logout'
                );
        }else{
            next();
        }
    },function(req,res,next){
        if('/'==req.url&&'GET'==req.method){

            ].join(''));
        }else{
            next();
        }
    },function(req,res,next){
        if('/login'==req.url&&'POST'==req.method){
            res.writeHead(200);
            if(!users[req.body.user]||req.body.password!=users[req.body.user].password){
                res.end('Bad username/password');
            }else{
                req.session.logged_in=true;
                req.session.name=users[req.body.user].name;
                res.end('Authenticated!');
            }
        }else{
            next();
        }
    },function(req,res,next){
        if('/logout'==req.url){
            req.session.logged_in=false;
            res.writeHead(200);
            res.end('Logged out!');
        }else{
            next();
        }
    }
);

server.listen(3000);

如果不使用connect-redis模块持久化session，代码是可以正常运行的，所以问题出在哪里呢，是node版本太新的缘故吗？
