未导入的pwntools python

Question

$ apt-get update
$ apt-get install python2.7 python-pip python-dev git libssl-dev libffi-dev build-essential
$ pip install --upgrade pip
$ pip install --upgrade pwntools

在运行上面的命令来安装pwntools之后，当我转到python并导入pwntools时，它将显示以下错误。

Answer 1

这是因为ENUM_P_TYPE不是在/usr/lib/pythonXX/site-packages/elftools/elf/enums.py中，而是在ENUM_P_TYPE_BASE中，所以有一种解决方案将ENUM_P_TYPE更改为/usr/lib/pythonXX/site-packages/pwnlib/elf/elf.py中的ENUM_P_TYPE_BASE。(只有两个位置:第54行和第1749行)

多亏了这个职位 (学分)，我们找到了解决方案。

Answer 2

由于指出 by @wujiechao，也许在等待pwntools修复发布时最好的选择是恢复到以前版本的pyelftools模块：

python2.7 -m pip install --upgrade pyelftools==0.24
