ubuntu18.04安装ns3

安装 NS-3 网络模拟器
为了在 Ubuntu 18.04 上成功安装 NS-3 (Network Simulator 3)，可以遵循以下指导：
准备工作环境
确保系统是最新的状态，这可以通过运行命令来实现：
sudo apt update && sudo apt upgrade -y
登录后复制
安装必要的依赖项
对于 C++ 编译以及构建工具的需求，应先安装这些基础组件。具体来说，需要安装 g++、python3 和 cmake 来支持编译过程[^2]:
sudo apt install g++ python3 cmake
登录后复制
除了上述基本需求外，还需要额外的一些库和支持软件以便更全面的支持 NS-3 的功能特性。这部分可通过如下指令完成安装：
