python - py2app: modulegraph 缺少 scan_code

Question

出于某种原因，我无法解释或谷歌，即使使用最简单的示例，py2app 也会让我崩溃。我使用的是创建为 Projects/Test/virtenv 的 python 3.4.1 虚拟环境，它通过 pip 安装了 py2app。

这是 $pip list 的输出:

altgraph (0.12)
macholib (1.7)
modulegraph (0.12)
pip (1.5.6)
py2app (0.9)
setuptools (3.6)

foo.py 是保存在 Projects/Test/中的 hello world 示例文件，包含一行:

print('hello world')

setup.py 保存在 Projects/Test 中，由 $py2applet --make-setup foo.py 生成:

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

Usage:
    python setup.py py2app
"""

from setuptools import setup

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

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

这是运行 $python setup.py py2app 的完整输出(所有 pip 和 python 命令都是在激活虚拟环境的情况下完成的):

谁能解释一下这是怎么回事以及如何解决它？

编辑:here是 modulegraph.py 中 scan_code 的文档，但是在 Projects/Test/virtenv/lib/python3.4/site-packages/modulegraph/modulegraph.py 中找到的文件包含一个名为 _scan_code 的函数，带有前导下划线。这是破坏 py2app 的某种类型的更改吗？

编辑:发布this

编辑:从提到的文件中的几个函数定义中手动删除前导下划线允许 py2app 运行而不会出错。我仍然对发生的事情感到困惑

我遇到了和你一样的问题，现在解决了。

我提到了这个post .

首先，搜索路径

$ /yourenv/lib/python2.7/site-packages/py2app/recipes/virtualenv.py

接下来，打开这个文件virtualenv.py，寻找scan_code或load_module并将其更改为_scan_code或 _load_module。

最后，尝试运行您的应用
