Firebase user authentication with AngularFire

Question

I am trying to authenticate the user through Github using AngularFire but I keep getting the error:

ref.authWithOAuthPopup is not a function

This is my controller code:

.controller('HomeCtrl', ['$scope', function($scope) {
    var ref = new Firebase("https://<MY-FIREBASE-APP>.firebaseio.com");
    function authHandler(error, authDat) {
        if (error) {
            console.log("Login Failed!", error);
        } else {
            console.log("Authenticated successfully with payload: ", authData);
        }
    }
    ref.authWithOAuthPopup("github", authHandler);
}]);

原来我使用的是旧版本或Firebase本身...我使用的是1.0.18版，而当前的版本是2.2.9。
