py2app:modulegraph缺少scan_code

Question

由于某些原因我无法解释或google,即使用最简单的例子,py2app也会崩溃.我使用python 3.4.1虚拟环境创建,Projects/Test/virtenv其中py2app通过pip安装.

这是输出$pip list:

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

foo.py是一个保存在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,生成者$py2applet --make-setup foo.py:

"""
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'],
)

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

有人可以解释一下发生了什么以及如何解决它？

编辑:这是modulegraph.py中scan_code的文档,但在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.这种变化是否打破了py2app？

编辑:发布此

编辑:从上述文件中的几个函数定义中手动删除前导下划线,允许py2app无错误地运行.对于发生的事情,我仍然感到困惑

Answer 1

我和你有同样的问题,现在解决了.

我提到了这篇文章.

首先,搜索路径

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

接下来,打开此文件virtualenv.py,查找scan_code或load_module将其更改为_scan_code或_load_module.

最后,尝试运行您的应用
