py2app问题，得到错误

Question

我正在尝试测试py2app的功能，用于创建独立的mac应用程序。我为我的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'],
)

我正试着制作一个简单的应用程序，用GUI来表达你的世界。以下是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，会出现一些错误。当我运行'python setup.py py2app‘

在这些错误发生之后，py2app似乎像往常一样运行，但当然应用程序本身无法工作。这里发生什么事情？我该怎么解决这个问题？

这也是终端输出的最后一行。

Answer 1

有一个小黑客可以解决这个问题，

1. 转到path /Users/Apollo/miniconda/lib/python2.7/site-packages/macholib/MachOGraph.py并打开这个文件。
2. 在第49行，将loader=loader.filename更改为loader_path=loader.filename

再次运行setup.py。
