I made an app with python py2app, but error message

# -*- coding: utf-8 -*-
from setuptools import setup

# Information such as name, description, version, etc. is the same as the general setup.py.
setup(name="test_py2xxx",
      description="py2app test application",
      version="0.0.1",
      # Add dependency on installation
      setup_requires=["py2app"],
      app=["byulcom.py"],
      options={
          "py2app": {
              # Includes modules required for PySide operation.
              "includes": ["PySide.QtCore",
                           "PySide.QtGui",
