Example from README fails with: type 'exceptions.TypeError'>:__init__() takes exactly 2 arguments (1 given)

Example from README fails on Ubuntu 16.04 x64 with:

$ python examples/simple.py 33333 echo
echo server running on port 33333
error: uncaptured python exception, closing channel <rediserver.net.RedisProtocolHandler connected 127.0.0.1:38936 at 0x7f29dd442bd8>
(<type 'exceptions.TypeError'>:__init__() takes exactly 2 arguments (1 given)

I did everything exactly as README says with one exception: I didn't run server in the background:

sudo apt-get install python-setuptools python-redis redis-tools

git clone https://github.com/ninowalker/py-redis-server.git

cd py-redis-server
python setup.py build

python examples/simple.py 33333 echo

In another console:
redis-cli -p 33333 hello world
