I use protobuf version 3.0.0b2.post2 and it works.

[danielferrer]

Same for me, tried with protobuf 3.0.0.b2.post2, 3.0.0.beta3, 3.0.0.beta2, six-1.10.0 same ocurs. Tried with python 3.4 and 3.5 on CentOS (IUS python repo):

[danielferrer]

By the way, it works ok in python 2.6.6 (python 2.6 from CentOS 6).
In python 3.4/3.5 it gave me the error mentioned in issue when receiving a mesage: "TypeError: unsupported operand type(s) for &: 'str' and 'int'"

[kartikgola]

Is there any workaround to this ?

[tawanda]

workaround is to use my branch for now, just ignored the error. I only tested this with text messages

pip install git+https://github.com/tawanda/yowsup.git#egg=yowsup

[ricardojlrufino]

Confirmed that it works in Python 3.4

pip install git+https://github.com/tawanda/yowsup.git#egg=yowsup

I use virtual env

virtualenv -p which python3 env
. env/bin/activate
pip3.4 install git+https://github.com/tawanda/yowsup.git#egg=yowsup

NOTE: Use the shell "bash" I had problems with zsh

@ricardojlrufino You can do
sudo pip3 install 'git+https://github.com/tawanda/yowsup.git#egg=yowsup'

[tawanda]

Dont use sudo with pip installs or you will install in the root python rather than the virtual env
