背景
从友方那边获得了pyc文件,但是由于他当时用的是python2.6编译的,而现在python2.6几乎被淘汰掉了,安装了python2.7 等其他版本无法运行该pyc文件,报错 RuntimeError: Bad magic number in .pyc file 。
安装了python 2.6 后,运行该文件不报错,但是依赖模块openbabel,openbabel在python2.6中安装稍微麻烦了一点,也不能直接使用python2.7中openbabel模块。因此尝试反编译pyc文件。
解决方案: 1. 反编译
2. 用对应版本的python 运行。不停尝试多种版本。
这里总结了不同版本对应的magic number.
You can get the magic number of your Python as follows:
$ python -VPython 2.6.2# python>>> import imp>>> imp.get_magic().encode('hex')'d1f20d0a'
To get the magic number for a pyc file you can do the following:
>>> f = open('test25.pyc')>>> magic = f.read(4)>>> magic.encode('hex')'b3f20d0a'>>> f = open('test26.pyc')>>> magic = f.read(4)>>> magic.encode('hex')'d1f20d0a'
安装
python2764.exe -m pip install uncompyle6
HitProfiler> uncompyle6.exe -h
Usage:
uncompyle6 [OPTIONS]... [ FILE | DIR]...
uncompyle6 [--help | -h | --V | --version]
Examples:
uncompyle6 foo.pyc bar.pyc # decompile foo.pyc, bar.pyc to stdout
uncompyle6 -o . foo.pyc bar.pyc # decompile to ./foo.pyc_dis and ./bar.pyc_dis
uncompyle6 -o /tmp /usr/lib/python1.5 # decompile whole library
----------------------------------------------------------------------------------------
运行 uncompyle6.exe .\ppi.pyc >ppi.py
获得了ppi.py,
然后用python27 成功运行ppi.py。 问题解决
