如何反编译pyc

uncompyle2 是一个可以将pyc文件转换为py源码的工具

下载地址：https://github.com/wibiti/uncompyle2

安装： setup.py install

 

参数：

Usage: uncompyle2 [OPTIONS]... [ FILE | DIR]...

Examples:

uncompyle2 foo.pyc bar.pyc # decompile foo.pyc, bar.pyc to stdout

uncompyle2 -o . foo.pyc bar.pyc # decompile to ./foo.dis and ./bar.dis

uncompyle2 -o /tmp /usr/lib/python1.5 # decompile whole library

Options:

-o <path> output decompiled files to this path:

if multiple input files are decompiled, the common prefix

is stripped from these names and the remainder appended to

<path>

uncompyle -o /tmp bla/fasel.pyc bla/foo.pyc

-> /tmp/fasel.dis, /tmp/foo.dis

uncompyle -o /tmp bla/fasel.pyc bar/foo.pyc

-> /tmp/bla/fasel.dis, /tmp/bar/foo.dis

-s if multiple input files are decompiled, the common prefix

is stripped from these names and the remainder appended to

<path>

uncompyle -o /tmp /usr/lib/python1.5

-> /tmp/smtplib.dis ... /tmp/lib-tk/FixTk.dis

-c <file> attempts a disassembly after compiling <file>

-d do not print timestamps

-m use multiprocessing

--py use '.py' extension for generated files

--norecur don't recurse directories looking for .pyc and .pyo files

--verify compare generated source with input byte-code

(requires -o)

--help show this message

Debugging Options:

--showasm -a include byte-code (disables --verify)

--showast -t include AST (abstract syntax tree) (disables --verify)

Extensions of generated files:

'.pyc_dis' '.pyo_dis' successfully decompiled (and verified if --verify)

'.py' with --py option

+ '_unverified' successfully decompile but --verify failed

+ '_failed' uncompyle failed (contact author for enhancement)

参数其实就是C:\Python27\Scripts\uncompyle2   文件里面， uncompyle2也是一个py文件但没有py扩展

 

代码如下：

1 #! /usr/bin/env python 2 import os 3 import sys 4                 5 def displayFile(file): 6     unPath= sys.executable 7     unPath=unPath[ 0 : unPath.rfind( os.sep ) ] 8     newname = file[0:file.rfind('.')] + '.py' 9     command = "python -u "+unPath+"\scripts\uncompyle2 " + file + ">" + newname10     try:11         os.system(command)12     except e:13         print file14     15 if __name__ == '__main__':16     print 'init'17     displayFile('C:\\pycc.pyc')18     print 'finished'

经过测试 反编译后生成的py 执行报错：

SyntaxError： Non-ASCII character '\xd6' ***** but no encoding declared

一看就知道是编码问题， 说有在生成的py文件的头部加

# -*- coding: gbk -*-

很奇怪，# -*- coding: UTF8 -*- 也会报错
