python-3.x - "installing"开泰结构Python

Question

我需要有关在笔记本电脑上安装 Kaitai Struct 的帮助。

我安装了 python-kaitaistruct 并编译了网络文件。

但是我得到一个导入错误:

Traceback (most recent call last):
  File "test2.py", line 1, in <module>
    from ethernet_frame import *
  File "/home/bene/python/ethernet_frame.py", line 15, in <module>
    from ipv6_packet import Ipv6Packet
  File "/home/bene/python/ipv6_packet.py", line 17, in <module>
    from ipv4_packet import Ipv4Packet
  File "/home/bene/python/ipv4_packet.py", line 17, in <module>
    from ipv6_packet import Ipv6Packet
ImportError: cannot import name 'Ipv6Packet

我的文件夹是这样的:

-rw-r--r--  1 bene bene  986  5. Jan 12:09 windows_systemtime.py

和我执行的文件:

from ethernet_frame import *
import socket

s = socket.socket(socket.AF_PACKET,socket.SOCK_RAW,socket.ntohs(3))

def network(buf):
    io = BytesIO(buf)
    ksio = KaitaiStream(io)
    pkt = EthernetFrame(ksio)
    dummy = pkt.ipv4_body.src_ip_addr
    print(dummy)

while True:
    p = s.recvfrom(65565)
    network(p) 

谁能帮帮我，也许我安装错了？ 或者如何安装和使用它的完整指南会很酷:DD

谢谢<3

我有一个类似的问题，在检查编译器创建的 .py 文件后，我发现编辑导入序列解决了这个问题。示例:

import ipv4_packet 导致了与您相同的错误。

我检查了 ipv4_packet.py，它有一个导入语句 from ipv6_packet import Ipv6Packet。

        # This is a generated file! Please edit source .ksy file and use kaitai-struct-compiler to rebuild

from pkg_resources import parse_version
from kaitaistruct import __version__ as ks_version, KaitaiStruct, KaitaiStream, BytesIO
from enum import Enum


if parse_version(ks_version) < parse_version('0.7'):
    raise Exception("Incompatible Kaitai Struct Python API: 0.7 or later is required, but you have %s" % (ks_version))

from udp_datagram import UdpDatagram
from tcp_segment import TcpSegment
from ipv6_packet import Ipv6Packet
from icmp_packet import IcmpPacket

class Ipv4Packet(KaitaiStruct):

    class ProtocolEnum(Enum):

ipv6_packet 尝试从 ipv4_packet 导入类:from ipv4_packet import Ipv4Packet，并导致导入错误。如果行 (ipv4_packet .py):

from udp_datagram import UdpDatagram
from tcp_segment import TcpSegment
from ipv6_packet import Ipv6Packet
from icmp_packet import IcmpPacket

被移动到类定义之后没有错误。

今天早上第一次玩 Kaitai Struct，我确信这不需要手动完成，我/我们正在做的编译中有一个问题，但如果你只是想拥有，这是可行的快速播放。
