在从github clone下来到ns-3/src/ndnSIM时忽略了两个文件的克隆失败
分别是NFD和ndn-cxx
提示如下：
Cloning into '/mnt/c/Users/29538/ndnsim/ns-3/src/ndnSIM/NFD'...
fatal: unable to access 'https://github.com/named-data-ndnSIM/NFD/': GnuTLS recv error (-110): The TLS connection was non-properly terminated.

Failed to clone 'NFD' a second time, aborting
解决方案为：
在ndnsim/ns-3/src/ndnsim 下
git clone --recursive https://github.com/named-data-ndnSIM/NFD.git
git clone --recursive https://github.com/named-data-ndnSIM/ndn-cxx.git
或者
git clone --recursive git://github.com/named-data-ndnSIM/NFD.git
git clone --recursive git://github.com/named-data-ndnSIM/ndn-cxx.git
