I have some troubles with py2app; for some reason I have always the same error for all scripts that I developed. At the moment I am using last MacPorts version and after two days of testing I cannot figure out what is wrong.

One of the setup.py file for py2app is:

from setuptools import setup

APP = ['main.py']
OPTIONS = {'argv_emulation': True, 'includes': ['sip', 'PyQt4._qt', 'PyQt4.QtCore', 'PyQt4.QtGui'],
    'excludes': ['PyQt4.QtDesigner', 'PyQt4.QtNetwork', 'PyQt4.QtOpenGL', 'PyQt4.QtScript', 'PyQt4.QtSql', 'PyQt4.QtTest', 'PyQt4.QtWebKit', 'PyQt4.QtXml', 'PyQt4.phonon']}

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

And this is the log:

python setup.py py2app

Thanks for any help.

问题是一些错误的输入已传递给算法，该算法试图检测依赖关系以便将它们打包到您的应用程序中 - 我遇到问题的地方之一是在包 README 中使用 github 风格的降价。 md 文件。

这是调试 setup.py 问题的一般指南，或者实际上是一般的 python 问题。

  1. 以交互模式再次运行它，即python -i setup.py py2app. 退出setup.py后，您会发现自己处于 python 提示符中。

  2. 运行from pdb import pm; pm()。您现在应该发现自己处于调试提示符下。

  3. 键入up并按 Enter - 您现在是堆栈中更高的帧 - 您可以键入list以查看当前帧在源代码中的位置，并args查看传递给当前帧的参数（通常是函数或方法）。您还可以运行 python 命令来检查当前状态，并运行pp var以漂亮地打印该变量。

  4. 重复上述步骤几次后，您会发现错误出现的位置 - 如果我遇到的是 README 文件，我发现了一个名为的变量lineno，它给出了导致错误的 README 文件的行。如果您的问题是模块导入，它可能会有所不同，但我的直觉是，您会发现自己packages在堆栈跟踪中看到的参数上循环，当前列表项将是您问题的关键。
