解决 1.1 sudo apt-get upgrade openssl? 2. export LD_LIBRARY_PATH="/usr/local/lib"
报错2：fatal: unsafe repository ('/home/xxx/Downloads/mini-ndn/dl/mininet-wifi' is owned by someone else) To add an exception for this directory, call:
?git config --global --add safe.directory /home/xxx/Downloads/mini-ndn/dl/mininet-wifi
暂时解决方案：
-
--no-wifi跳过 Mininet-WiFi 依赖。目前 Mininet-WiFi 仅适用于 Ubuntu，因此在其他发行版上安装时必须指定此选项。
