Import from elftools is failing

[matedealer]

When installing the newest version of pwntools in a fresh venv, "from pwn import *" failing in a python console:

>>> from pwn import *
Traceback (most recent call last):

ImportError: cannot import name ENUM_P_TYPE

I guess the new version of elftools may be the problem ( https://pypi.org/project/pyelftools/0.25/ )

[wujiechao]

Due to ENUM_P_TYPE not in /usr/lib/pythonXX/site-packages/elftools/elf/enums.py, but ENUM_P_TYPE_BASE in it, so there is a solution that change the ENUM_P_TYPE to ENUM_P_TYPE_BASE in /usr/lib/pythonXX/site-packages/pwnlib/elf/elf.py. (Just 2 places: line 54 and line 1749)

tips: This solution can solve some friends' problem, but in some cases, will bring other problem. Another solution for solve the whole problem is to reduce your pyelftools version to 0.24.

I am still having the same issue. I have changed ENUM_P_TYPE to ENUM_P_TYPE_BASE on line 54 and line 1749 in elf.py. I assume I have to recompile the elf.py after these changes? However, I am getting some permission errors when trying to recompile. Any thoughts?

FIX: I had to change permission on my elf.pyc file so that it would recompile. Now it is working properly.
