Meteorjs typeError: Accounts.createUser is not a function

Im having an error when I try to manually create a user on my meteorjs+angular app.

Here is my server code:

Meteor.methods({
   createNewUser: function(userInfo){
        Accounts.createUser(userInfo);
    }
});

Im calling that using angular-meteor in this way:

$scope.save = function(){
      $meteor.call('createNewUser', $scope.account);
}

And the error goes like this:

Exception while simulating the effect of invoking 'createNewUser' TypeError: Accounts.createUser is not a function....

My .meteor/packages file:

meteor-platform
twbs:bootstrap
pfafman:font-awesome-4
urigo:angular
angularui:angular-ui-router
aldeed:collection2
underscore
accounts-password
