Плагин Babel 5 (объект-назначение) запускается вместе с Babel 6

Question

После обновления зависимостей проекта я начал видеть эту ошибку, кажется, есть проблема с версионированием object-assign Вавилон 5 плагин.

После обновления я использую Babel 6, ближайший плагин, который я смог найти, это es6-object-assign, но его использование приводит к ошибке (ошибка показана ниже).

Использование browserify + babelify + object-assign в моем приложении:

var babelify = require('babelify');
var browserify = require('browserify-middleware');
var keystone = require('keystone');

var importRoutes = keystone.importer(__dirname);

// Setup Route Bindings
exports = module.exports = function(app) {
    app.use('/js', browserify('./client/scripts', {
        transform: [babelify.configure({
            plugins: ['object-assign']
        })]
    }));
    // Views
    app.use(function(req, res) {
        res.render('index');
    });
};

Ошибка при переходе на plugins: ['es6-object-assign']наверное потому что babelify требует оригинала object-assign пакет в node_modules/babelify/index.js онлайн var assign = require("object-assign");:
