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,
Fujimoto

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
I tried to reinstalled Ryu for many times but this error cannot be
solved. Could you please help me on it?
Thanks.
