py2app问题，出现错误

我正在尝试测试py2app的功能，以创建独立的mac应用程序。我为测试代码生成了一个名为“ hello.py”的安装文件。

"""
This is a setup.py script generated by py2applet

Usage:
python setup.py py2app
"""

from setuptools import setup

APP = ['hello.py']
DATA_FILES = []
OPTIONS = {'argv_emulation': True}

setup(
   app=APP,
   data_files=DATA_FILES,
   options={'py2app': OPTIONS},
   setup_requires=['py2app'],
)

而且我正在尝试制作一个简单的应用程序，该应用程序仅通过GUI来向您问好世界。这是hello.py的代码

import sys
from PyQt4 import QtGui
from PyQt4 import QtCore

app = QtGui.QApplication(sys.argv)

widget = QtGui.QLabel("Hello World")
widget.show()


app.exec_()

上面的脚本运行得很好，但是当我尝试使用py2app时，出现了一些错误。当我运行'python setup.py py2app'

发生这些错误后，py2app似乎可以正常运行，但是应用程序本身无法正常工作。这里发生了什么？我该如何解决？

这也是终端输出的最后一行。
