安装包的依赖关系如此之多'nmap'

Question

我想通过命令 apt-get 在 debian 上安装包 nmap，但是似乎包 nmap 依赖于这么多依赖项！例如它依赖于包 imagemagick 和 x11-common！除非 nmap 需要 X window 系统！？一切都好吗？

# apt-get install nmap

这是 Debian 7 wheezy (oldstable) which was fixed in Debian 8 jessie (stable). Nmap requires the liblinear1 package in order to do IPv6 OS detection, and that package had a "recommends" dependency on liblinear-tools, which further recommended libsvm-tools, which requires gnuplot, and that is where the X11 dependencies are coming from. In Debian jessie and later releases, liblinear1 上的一个问题，已将对 liblinear-tools 的依赖性降级为 "suggests"，因此这不是问题。

要解决您的特定问题，您可以升级到更新的 Debian 版本，或使用 apt-get --no-install-recommends install nmap。不过，更好的解决方案是使用从源代码构建或从官方 RPM 安装的最新版本的 Nmap。您可以使用 alien to install RPMs on a Debian system. The version of Nmap that Debian wheezy installs (6.00) is over 3 years old and has several known bugs. Debian jessie is on the (current) latest stable version, 6.47, but that is also a year old and about to be eclipsed. The latest version can always be downloaded from https://nmap.org/download.html
