HI,
Hmm, I don't know about your environment, so I can't give you a
specific solution...
Please ask to the owner of your machine.
Thanks,
Fujimoto

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.

Hi,
The error message says that Ryu is trying to output the log into
"var/log/ryu/ryu.log", but
"var/log/ryu/" directory is missing.
By default, Ryu does not output the log into such place (does not
output log file).
https://github.com/osrg/ryu/blob/e1e85052f5563f120b1e62fd9282946be6154f5b/ryu/log.py#L40-L41

Did you specify "--log-dir" or "--log-file" option to ryu-manager?
Or creating "var/log/ryu/" directory should solve this problem, I
guess.
Thanks,

Hi,
I am new on Ryu. When I tried to run the controller of Ryu, I
always got this error and I could not find this file, ryu.log. I
think I installed Ryu incorrectly but I followed this link step
by step: https://github.com/osrg/ryu/wiki/OpenFlow_Tutorial
<https://github.com/osrg/ryu/wiki/OpenFlow_Tutorial>
I tried to reinstalled Ryu for many times but this error cannot
be solved. Could you please help me on it?
Thanks.
