py2app:modulegraph缺少scan_code [英] py2app: modulegraph missing scan_code

问题描述

由于某种原因，我无法解释或使用google，即使使用最简单的示例，py2app也会崩溃.我正在使用创建为 Projects/Test/virtenv 的python 3.4.1虚拟环境，该环境通过pip安装了py2app.

这是 $ pip list 的输出:

  altgraph(0.12)macholib(1.7)模组图(0.12)点(1.5.6)py2app(0.9)设置工具(3.6) 

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

  print('hello world') 

setup.py保存为由 $ py2applet --make-setup foo.py 生成的项目/测试:

 "这是由py2applet生成的setup.py脚本用法:python setup.py py2app"从setuptools导入安装程序APP = ['foo.py']DATA_FILES = []选项= {'argv_emulation':真}设置(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):

有人可以解释发生了什么事以及如何解决吗?

此处是modulegraph.py中scan_code的文档，但是在Projects/Test/virtenv/lib/python3.4/site-packages/modulegraph/modulegraph.py中找到的文件包含名为_scan_code的函数，并带有下划线.是这种破坏了py2app的更改吗?

发布此

从上述文件中的几个函数定义中手动删除前划线，使py2app可以正常运行.我仍然对发生的事情感到困惑

解决方案

我遇到了与您相同的问题，并已解决.

我提到了此帖子

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 并将其更改为 _scan_code 或 _load_module .

最后，尝试运行您的应用

For some reason I can't explain or google, py2app crashes on me even with the simplest examples. Im using a python 3.4.1 virtual environment created as Projects/Test/virtenv which has py2app installed via pip.

Here is the output of $pip list:

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

foo.py is a hello world example file saved in Projects/Test/ and contains a single line:

print('hello world')

setup.py is saved in Projects/Test as generated by $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'],
)

Here is the full output of running $python setup.py py2app (all pip and python commands were done with the virtual enviroment activated) :

    mf.scan_code(co, m)
AttributeError: 'ModuleGraph' object has no attribute 'scan_code'

Can someone please explain whats going on and how to fix it?

EDIT: here is the documentation for scan_code in modulegraph.py, however the file found in Projects/Test/virtenv/lib/python3.4/site-packages/modulegraph/modulegraph.py contains a function called _scan_code with a leading underscore. Is this some type of change that broke py2app?

EDIT: posted this

EDIT: Manually removing leading underscores from a couple function definitions in the file mentioned allowed py2app to run without error. I'm still confused regarding what happened

解决方案

I had the same problem as you and solved it now.

I referred to this post.

First, search for the path

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

Next, open this file virtualenv.py, look for scan_code or load_module and change it to _scan_code or _load_module.

Last, try to run your app
