python-3.8 - 导入错误 : cannot import name 'AnsweringMachine' from partially initialized module 'scapy.ansmachine'

Question

当我使用 scapy.layers.inet.IP 包时，结果显示导入错误:无法从部分初始化的模块“scapy.ansmachine”中导入名称“AnsweringMachine”。

我很困惑，这是我的 python 演示。

import hashlib
import time

from scapy.layers.inet import ICMP, IP
from scapy.sendrecv import sr1

SUCCESS = 100001
FAILURE = 100002

def random_str_byte():
    temp = hashlib.md5()
    temp.update(bytes(str(time.time()), encoding='utf-8'))
    result = temp.hexdigest()
    return bytes(result, encoding='utf-8')


def ping(target_ip):
    package = IP(dst=target_ip)/ICMP()/random_str_byte()
    result = sr1(package, timeout=3, verbose=False)
    if result:
        return target_ip, SUCCESS
    else:
        return target_ip, FAILURE


if __name__ == '__main__':
    a = ping('XX.XX.XX.XX')
    print(a)

错误信息是

你能给我一些建议或解决方案吗？谢谢。

from scapy.layers.inet import ICMP, IP

直接导入inet导致这个问题。取而代之的是，尝试导入

from scapy.all import *

这将引入 ICMP、IP 和 scapy.layers.inet 中的所有其他内容

或

import scapy.all as scapy

并用 scapy.IP 替换 IP，用 scapy.ICMP 替换 ICMP
