python3将exe 转支持库错误 AssertionError: None does not smell like code

exe -> pyc包(*.exe_extracted)

安装反编译工具

exe反编译工具：pyinstxtractor.py下载：https://sourceforge.net/projects/pyinstallerextractor/

python pyinstxtractor.py hello.exe

包反编译

懒的写！！！ 这有详细说明

https://blog.csdn.net/qq_45100200/article/details/128485152

支持库部分（重点）

需要工具 uncompyle6

pip install uncompyle6

反编译

支持库一般是 PYZ-00.pyz_extracted 文件夹

命令

uncompyle6 hello.pcy -> hello.pc 

反编译错误！

由于支持库的pyc 文件也缺少了一部分
8-12字节的描述符
所以反编译会报 AssertionError: None does not smell like code

解决办法 手动补全

手动替换08–12 的字节(08-11 插入 12-15改写)

改写为以下内容

脚本处理（人类因为懒 才有了文明的进步）

不废话 直接上脚本

# -*- encoding:utf-8 -*-# uncompyle6 支付库 pcy -> py
# 错误 AssertionError: None does not smell like code
# 由于在 第8字节缺少4字节描述符 导致失败 _PCY_Z_ADDBYTES
# 将 _PCY_Z_ADDBYTES 填入后完成
