python - cx_freeze : How do I resolve conflicts caused by multiple . 同名dylib文件

Question

我已经创建了一个 python 应用程序，现在我想将它变成一个独立的应用程序。我正在使用 virtualenv 中的 cx_freeze，它以前在我的机器上使用依赖性较低的脚本运行。

我目前遇到一个问题，当它尝试将同名的 dylib 文件复制到构建文件夹时，cx_freeze 出错。

我正在运行命令:

python3 setup.py build

我的 setup.py 文件如下所示:

from cx_Freeze import setup, Executable

build_options = {'packages': ["PySimpleGUI", "matplotlib", "pandas", "descartes", "geopandas", "cities_coordinates"],
                 #'excludes': ["PIL", "pyproj", "setuptools"],
                 "zip_exclude_packages": [],}

import sys
base = 'Win32GUI' if sys.platform=='win32' else None

executables = [
    Executable('main.py', base=base, targetName = 'data_visualizer')
]

setup(name='data_visualizer',
      version = '0.1',
      description = 'Data visualization tool',
      options = {'build_exe': build_options},
      executables = executables)

这是我遇到的错误:

如果我排除引入与另一个 dylib 冲突的库(请参阅 setup.py 中注释掉的排除构建选项)，那么该命令将成功运行，但我构建的应用程序将由于缺少依赖项而失败。

有谁知道解决这个问题的方法吗？

一些其他信息(如果重要的话)->

操作系统: Mac OS Big Sur
Python版本:3.7.8
cx_freeze 版本:6.2

Answer 1

似乎已在此 cx_Freeze issue 中报告了同名错误，由此介绍pull request将第二个文件复制到另一个文件的路径时会引发错误。

A workaround被合并以打印警告并简单地使用文件的第一个副本而不是引发错误。由于它似乎尚未发布(截至 2021 年 3 月 9 日，v6.5.3)，我从 Git 安装了 cx_Freeze(在克隆并进入 repo 后，我通过 pip install -e 安装了它。 )，运行 cxfreeze，并看到如下警告:

*** WARNING ***

Using only source 1.

冲突文件被简单地跳过，允许构建继续进行。
