无法从scapy模块中找到Ether类

Question

我一直收到一个错误，说Ether()方法没有在我的脚本中定义。我使用的是python2.7，arprequest和arpresponse变量在类的函数中。我跟着一个tutourial，它是完全相同的代码。还有一个包含相同代码的项目https://github.com/OsandaMalith/ARP-Spoofer/blob/master/arp.py (第171行)

from scapy import *
            arprequest = Ether(dst='ff:ff:ff:ff:ff:ff')/ARP(pdst=ip+str(i), hwdst='ff:ff:ff:ff:ff:ff')
            arpresponse = srp1(arprequest, timeout=2, verbose=0)

导入不正确，它应该来自all模块。

from scapy.all import *

如果您想要直接导入，scapy.layers.l2中提供了Ether。
