Hi Fujimoto,
Thanks for help. I didn't specify any thing for ryu-manager. I just
installed by typing "pip install ryu" and install some dependencies.
I tried to create "var/log/ryu" directory but I got a new error.
mkdir: cannot create directory "/var/log/ryu/": Permission denied.
Does it mean I don't have the permission to do it? I am the admin of this
OS.
Thanks.
