[IPython-dev] pyzmq: kernel.py doesn't work

[Ondrej Certik]

Hi,

this is what I get when tried the latest git zeromz+pyzmq:


ondrej at crow:~/repos/pyzmq/examples/kernel(master)$ ./kernel.py

and this is when I run the frontend:

  File "_zmq.pyx", line 676, in zmq._zmq.Socket.send_json (zmq/_zmq.c:4963)
TypeError: send_json() got an unexpected keyword argument 'ident'


I have installed pyzmq using:

./setup.py install --home=~/usr


I bet the problem is with some ident kwarg, I guess it should be easy to fix it.
