问题描述
我试过运行我的程序,我试过 import Condition list comprehension: 1.7542460000000002
C:\Users\x\x\x\x\envs\lib\timeit.py:15: UserWarning: Boolean Series key will be reindexed to match DataFrame index.
-n/--number N: how many times to execute 'statement' (default: see below)
C:\Users\x\x\x\x\envs\lib\timeit.py:16: UserWarning: Boolean Series key will be reindexed to match DataFrame index.
-r/--repeat N: how many times to repeat the timer (default 5)
Condition and drop: 5.7606202
Group by: 0.44012989999999874
然后 import scapy
但它会给我同样的错误。如果有帮助,我正在使用 kali-linux。导致错误的代码来自 scapy.all
scapy.all import *
修复了它。你需要去:
Traceback (most recent call last):
File "/home/bradz/test.py",line 24,in <module>
from scapy.all import send,IP,TCP,ARP

with open(filename,'br') as thefile:
FileNotFoundError: [Errno 2] No such file or directory: b'liblibc.a'
并编辑该行
/usr/lib/python3/dist-packages/scapy/arch/bpf/core.py
到
LIBC = cdll.LoadLibrary(find_library("libc"))
解决方法
这似乎是库中的一个错误 fixed 11 days ago:
Python 3.9 中有一个回归,find_library()
功能:
>>> 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'
一种解决方法是改用 find_library("c")
。它也适用于
旧版本的 Python 已经在使用了
contrib/isotp.py
。
更新 scapy,因为您使用的 scapy 版本似乎与您的 CPython 版本不兼容。
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。
