Python 反编译工具uncompyle2

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：

 #! /usr/bin/env python
 import os
 import sys

 def displayFile(file):
     unPath= sys.executable
     unPath=unPath[ 0 : unPath.rfind( os.sep ) ]
     newname = file[0:file.rfind('.')] + '.py'
     command = "python -u "+unPath+"\scripts\uncompyle2 " + file + ">" + newname
     try:
         os.system(command)
     except e:
         print file

 if __name__ == '__main__':
     print 'init'
     displayFile('C:\\pycc.pyc')
     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
