Hi,

The requirements are updated in last week.
https://github.com/osrg/ryu/blob/master/tools/pip-requires

Please re-install the required packages and try again.
$ sudo pip install -r tools/pip-requires
$ sudo python setup.py install

Thanks,
Iwase

Thanks for trying the latest code! That's really helpful for making
sure that a release works nicely.

I tried to install the latest on clean Ubuntu 14.04 and got the
following:

***@fac4ef26269e:/ryu# pip install -r tools/pip-requires
Exception:

ValueError: ("Expected ',' or end-of-list in", "ovs >=2.6.0.dev0 ;
python_version >= '3.0'", 'at', " ; python_version >= '3.0'")

Now I remember that the version of pip on 14.04 can't handle the
version condition stuff. Jason, how about forcing >=2.6.0.dev0 for
everyone. Not necessary for guys with python2.7 but much better than
getting repeated error reports that Ryu 4.1 can't be installed on
14.04.

Works for me. I haven't seen any issues with the 2.6.0 branch in my
dev (python2) environment.

Thanks for the confirmation, pushed.
