python - cx-Freeze 无法构建“LookupError：未知编码”

问题描述

我在 Windows 10 64 位上有 Python 3.8。我在安装 cx-Freeze 时遇到了一些麻烦，不得不安装“cx_Freeze-6.0-cp38-cp38-win32.whl”，因为它是唯一一个有效的。

我正在尝试将使用 wxPyhton 生成简单 GUI 的脚本转换为可执行文件。

运行“steup.py build”时出现以下错误

running build

LookupError: unknown encoding: unicode-internal

我不知道为什么会出现这个错误。

设置.py：

import os
import sys

from cx_Freeze import Executable, setup

# Dependencies are automatically detected, but it might need
# fine tuning.
buildOptions = dict(
    packages = [],
    excludes = [],
    include_files=[]
)

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

executables = [
    Executable('test.py', base=base)
]

setup(name='editor',
      version = '1.0',
      description = '',
      options = dict(build_exe = buildOptions),
      executables = executables)
