python - 无法导入图层 xxx : name arp_display is not defined Python

Question

我有一个问题，这个简单的代码有一天停止工作，任何其他涉及 scapy 的代码都会给我带来类似的错误(无法导入层(我试图使用的层，arp，tcp ..)和函数名称)

这是代码:

from scapy.all import *
def arp_display(pkt):
    if pkt[ARP].op == 1: #who-has (request)
        return "Request: " + pkt[ARP].psrc + " is asking about " + pkt[ARP].pdst
    if pkt[ARP].op == 2: #is-at (response)
        return "*Response: " + pkt[ARP].hwsrc + " has address " + pkt[ARP].psrc
print sniff(prn=arp_display, filter="arp", store=0, count=1500)

这是错误:

我刚刚遇到了这个问题。我的桌面上有一些关于 DNS(dns 请求和 dns 重定向)的 python 脚本。运行这些脚本时，会出现一个同名但扩展名为 pyx(我相信)的新脚本，该脚本是在运行该脚本时创建的。解决方案？我删除了脚本和之后创建的脚本(dns_request.py 和 dns_request.pyx)。运行其他脚本时，警告消失了!
