Python Scapy-创建数据包并显示它将导致>；非类型对象没有属性'；路线'&书信电报；

我刚刚发现了一些奇怪的东西。 执行以下操作

>>> from scapy.layers.inet import Ether,IP,UDP
>>> e=Ether()
>>> i=IP()
>>> u=UDP()
>>> p=e/i/u
>>> p.show()

导致此错误

###[ Ethernet ]###

不知怎么的，似乎能解决它。这怎么可能？是否有一些特殊模块需要导入？

您也需要导入scapy route模块

from scapy import route
from scapy.layers.inet import Ether,IP,UDP
e=Ether()
i=IP()
u=UDP()
p=e/i/u
p.show()

from scapy import route
from scapy.layers.inet import Ether,IP,UDP
e=Ether()
i=IP()
u=UDP()
p=e/i/u
p.show()
