ndnSIM运行./waf 报错No module named ‘doxygen‘

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. fatal: clone of 'https://github.com/named-data-ndnSIM/NFD' into submodule path '/mnt/c/Users/29538/ndnsim/ns-3/src/ndnSIM/NFD' failed Failed to clone 'NFD'.

ndnSIM运行./waf 报错No module named ‘doxygen‘最先出现在Python成神之路。
