这是在安装scapy时遇到的

这两篇文章可以联合查看

问题2：curl: (23) Failed writing body (0 != 1371)

//解决方法如下
sudo curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
sudo python get-pip.py

重点是这个sudo，不要掉了

问题3：ERROR: This script does not work on Python 2.7 The minimum supported Python version is 3.7. Please use https://bootstrap.pypa.io/pip/2.7/get-pip.py instead.

 sudo curl https://bootstrap.pypa.io/pip/2.7/get-pip.py -o get-pip.py

这是在运行scapy时遇到的

问题1：error: [Errno 1] Operation not permitted

是因为权限不够

sudo su

问题2：WARNING: Mac address to reach destination not found. Using broadcast.

这里是网络的原因，可以重点解决ping不ping通的事。宿主机和虚拟机互相之间ping不ping通，两者ping不ping通网络。
tips：宿主机与虚拟机的子网掩码，默认网关一致

例：
arp -a//查看
ifconfig//查看
ifconfig enp0s3 IP地址  子网掩码
ifconfig enp0s3 broadcast 默认网关
//注意enp0s3是网卡，你和我的网卡不一定一样，用ifconfig 查看最左边的就显示的是网卡
