Ubuntu 16.04安装顺利，Ubuntu 18.04不成功。
NS-3和Ubuntu 16.04更配哦

使用bake安装
hg clone http://code.nsnam.org/bake
export BAKE_HOME=`pwd`/bake
export PATH=$PATH:$BAKE_HOME
export PYTHONPATH=$PYTHONPATH:$BAKE_HOME
检查之前预装的包：bake.py check
输出：
> Python - OK
> GNU C++ compiler - OK
> Mercurial - OK
> Git - OK
> Tar tool - OK
> Unzip tool - OK
> Make - OK
> cMake - OK
> patch tool - OK
> Path searched for tools:(一些路径)
碰到没有安装的包利用sudo apt-get install <package>指令再安装一下
安装ns-3：
bake.py configure -e ns-3.26
bake.py deploy
要很久，中间存在problem提示也不用管
最后输出successfully finished即可
编译 ns-3
进入~/home/source/ns-3.26 (也可能是别的路径，进入ns-3.26文件夹即可)
./waf configure --build-profile=debug --enable-examples --enable-tests
./waf build
编译完成之后，测试
./test.py -c core
./waf --run hello-simulator
输出Hello Simulator则成功
