嗯，我不认为方法createUserWithUsernameAndPassword works，

用这个来代替 createUserWithEmailAndPassword

当firebase使用电子邮件时，您使用了用户名

I'm trying to create user account using Firebase auth in nodejs. It doesn't work and I don't know why. Here's the code and the error generated by nodejs:

var config = {.......}; // i can't share the config

var app = firebase.initializeApp(config);

var db = app.database();
var auth = app.auth();

auth.createUserWithUsernameAndPassword("anemail@gmail.com", "@NewPassWord").then(
    function(user){ console.log(user);},
    function(error){ console.error(error);}
);

Error generate by NodeJS:

TypeError: Object [object Object] has no method 'createUserWithUsernameAndPassword'

well, I don't think that the method "createUserWithUsernameAndPassword" works,

Use this instead createUserWithEmailAndPassword

you used username when firebase use email
