javascript - 类型错误 : done is not a function

Question

我在我的项目中使用 passport.js 来验证和处理 session 。

我使用电子邮件从 Passport 进行身份验证，但是当在验证时调用 done 时，我收到错误 done is not a function。

at Promise.<anonymous> (/Users/sultan/Desktop/too2/controllers/users.js:39:28)
at Promise.<anonymous> (/Users/sultan/Desktop/too2/node_modules/mongoose/lib/promise.js:120:8) 

代码

  // LOCAL LOGIN =============================================================
passport.use('local-login', new LocalStrategy({
    usernameField : 'email',
    passwordField : 'password'
    //passReqToCallback : true // allows us to pass in the req from our route (lets us check if a user is logged in or not)
},
function( email, password, done) {
    if (email)
        email = email.toString().toLowerCase();

    // asynchronous
    process.nextTick(function() {
        User.findOne({ email:  email }, function(err, user) {
            // if there are any errors, return the error
            if (err)
                return done(err);

            // if no user is found, return the message
            if (!user)
        //(/Users/sultan/Desktop/too2/controllers/users.js:39:28)
                return done(null, false, {message: 'No user found.'});

            if (!user.validPassword(password))
                return done(null, false, {message: 'Oops! Wrong Password'});

            // all is well, return user
            else
                return done(null, user);
        });
    });

}));

此错误的原因是什么，我该如何解决？

这对我有用

passport.use('login', new LocalStrategy({
        // by default, local strategy uses username
        usernameField : 'email',
        passwordField : 'password',
        passReqToCallback : true
    },
    function(req, email, password, done) {
        if (email) email = email.toLowerCase();

        // asynchronous
        process.nextTick(function() {
            User.findOne({ 'email' :  email }, function(err, user) {
                // if there are any errors, return the error
                if (err)
                    return done(err);

                // if no user is found, return the message
                if (!user)
                    return done(null, false, req.flash('loginMessage', 'No user found.'));

                if (!user.validPassword(password))
                    return done(null, false, req.flash('loginMessage', 'Oops! Wrong password.'));

                // all is well, return user
                else
                    return done(null, user);
            });
        });

    }));
