Question

我在Windows上使用64位python 2.7。当我用cx_Freeze构建一个可执行文件然后运行它时，我得到一个错误窗口（，替换实名）：

---------------------------
cx_Freeze: Python error in main script

---------------------------
OK   
---------------------------

该文件不在存档中，但如果我在构建后手动添加它，则仍然找不到该文件。看起来像路径（反斜杠？）问题。

有人知道如何解决这个问题吗？

另外：你认为使用pyinstaller可以更好地解决这类问题吗？我选择cx_Freeze的原因是pyinstaller本身的安装看起来非常重要，而cx_Freeze只是一个单独的。

Answer 1

我在使用Py2exe时遇到了同样的问题。

我发现问题是由NetworkX版本1.10引起的

回滚到1.9.1对我有用：

pip uninstall networkx
pip install networkx==1.9.1

Answer 2

我不得不面对同样的问题，但无法回滚到networkx 1.9.1。

我通过从设置中排除lib2to3并使用＆＃34; includefiles＆＃34;将其包含回来解决了这个问题。：

# -*- coding: cp1252 -*-

import myproj
from os.path import dirname
from cx_Freeze import setup, Executable

gui=Executable(
     script="myproj/gui.py",
     base="Win32Gui",
     targetName="myproj.exe",
     icon="logo.ico",
     )

packages=[]
includefiles=[]
includes=[]
excludes=['tkinter', 'lib2to3']

import lib2to3
lib23_path = dirname(lib2to3.__file__)
includefiles.append(lib23_path)

setup(
      name = 'myproj',
      version = myproj.version,
      author='myself',
      license='...',

      options = {'build_exe': {
                               'packages':packages,
                               'include_files':includefiles,
                               'includes':includes,
                               'excludes':excludes,
                               }},
      executables = [gui],

      )

cx_Freeze和networkx的问题
