python scapy.all 找不到文件

Question

我试过运行我的程序，我试过导入 scapy 然后导入 scapy.all 但是会给我同样的错误。如果有帮助，我正在使用 kali-linux。导致错误的代码仅来自 scapy.all import *

这是完整的错误输出：

Traceback (most recent call last):
  File "/home/bradz/test.py", line 24, in <module>
    from scapy.all import send, IP, TCP, ARP
  File "/usr/local/lib/python3.9/dist-packages/scapy/all.py", line 16, in <module>
    from scapy.arch import *
  File "/usr/local/lib/python3.9/dist-packages/scapy/arch/__init__.py", line 27, in <module>
    from scapy.arch.bpf.core import get_if_raw_addr<br/>
  File "/usr/local/lib/python3.9/dist-packages/scapy/arch/bpf/core.py", line 30, in <module>
    LIBC = cdll.LoadLibrary(find_library("libc"))
  File "/usr/lib/python3.9/ctypes/util.py", line 341, in find_library
    _get_soname(_findLib_gcc(name)) or _get_soname(_findLib_ld(name))
  File "/usr/lib/python3.9/ctypes/util.py", line 147, in _findLib_gcc
    if not _is_elf(file):
  File "/usr/lib/python3.9/ctypes/util.py", line 99, in _is_elf
    with open(filename, 'br') as thefile:
FileNotFoundError: [Errno 2] No such file or directory: b'liblibc.a'

已修复。您需要前往：

/usr/lib/python3/dist-packages/scapy/arch/bpf/core.py

并编辑行

LIBC = cdll.LoadLibrary(find_library("libc"))

到

LIBC = cdll.LoadLibrary(find_library("c"))

库中的错误

There is a regression in Python 3.9 with the find_library() function:

>>> import ctypes.util
>>> ctypes.util.find_library("libc")
 Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
   File "/usr/lib/python3.9/ctypes/util.py", line 341, in find_library
     _get_soname(_findLib_gcc(name)) or _get_soname(_findLib_ld(name))
   File "/usr/lib/python3.9/ctypes/util.py", line 147, in _findLib_gcc
     if not _is_elf(file):
   File "/usr/lib/python3.9/ctypes/util.py", line 99, in _is_elf
     with open(filename, 'br') as thefile:
 FileNotFoundError: [Errno 2] No such file or directory: b'liblibc.a'

A workaround is to use find_library("c") instead. It also works in older versions of Python and that's already what's used in contrib/isotp.py.

更新 scapy，因为您使用的 scapy 版本似乎与您的 C 版本不兼容Python。

实际上，PyPI 似乎尚未更新，因此您将无法通过 pip 进行更新。您可能需要回滚 Python 版本，直到它更新，或者 manually install the patched scapy version from Github.
