【问题描述】：

我正在尝试在服务器中安装 scapy。但我收到错误。 1）我安装了pip，已经安装了python 2.66。 2）然后我运行命令 pip installed scapy

然后在终端中输入 scapy，我得到：

Welcome to Scapy (2.3.3)

现在我仍然可以使用 scapy 发送 tcp 数据包，但我收到校验和错误。所以我想知道校验和错误是否与上述错误有关？

【问题讨论】：

标签： python python-2.7 centos scapy

【解决方案1】：

此警告并未导致校验和错误。校验和错误是我的错误。我还发现了为什么会出现此错误。

此错误/警告是由于 python2.6 造成的。 Scapy 2 的更高版本需要 python >= 2.7

【讨论】：

【解决方案2】：

试试sudo python 可能会奏效。

欲知详情，see
