为什么pcapy不在我的Ubuntu18.04服务器上安装最新版本呢？

Question

我可以看到pcapy在0.11.4上：

https://pypi.org/project/pcapy/

对我来说，我似乎无法得到更晚的版本：

pip install pcapy

pcapy (0.10.8)

如何获得最新版本呢? 0.10.8似乎存在内存泄漏，虽然它在我的大型服务器上不是什么大问题，但它会在较小的服务器上引发问题，因为整个服务器只有4gb的内存。这正被用作Maltrail的依赖项。

编辑:当我尝试进行升级时：

root@ca1:/etc/fail2ban# pip install --upgrade pcapy

Answer 1

一如既往-你最终找到答案后，张贴！所以我不得不：

apt-get -y install schedtool libpcap-dev
pip2 install pcapy

现在，它正确地安装了最新版本。好了！
