How to install Python package pyzmq properly?

How to install Python paackage pyzmq properly?

I searched in Synapic package manager in vain.

Solution 1:

apt-cache search python zmq

returns

python-zmq - Python bindings for 0MQ library
python-zmq-dbg - Python bindings for 0MQ library - debugging files

Is this what you are looking for? Then

apt-get install python-zmq

should work.

For future searches:

Python modules in Debian and Ubuntu are often named differently:

python-<module name> where <module name> often does not contain "py" or "python".

Solution 2:

I got an error message like this when I tried to run ipython notebook on ubuntu 12.04

ImportError: IPython.html requires pyzmq >= 13, but you have 2.1.11

I tried

sudo pip uninstall pyzmq
sudo pip install pyzmq

but it didn't work. Finally, I solve the problem by

sudo pip install --upgrade pyzmq

Solution 3:

sudo apt-get install libzmq-dev
sudo easy_install pyzmq

This installed 2.2.0 version of libzmq-dev. pyzmq complained that it was 3.2.0 and features beyond 2.2.0 could not be used (since its base libzmq was 2.2.0). Tried loading it in python and it gave a whole bunch of errors.

So:

apt-get purge libzmq-dev

and installed libzmq after doing a git clone from the zmq git site. It installed the 3.2.0 version of libzmq just fine. However, trying to then install pyzmq gave errors like "timer_create undefined". One site said, I needed to update my Cython - which I did .. to ver. 19.x. Still same error. So uninstalled libzmq and pyzmq again.

Did a clean install using

sudo apt-get install python-zmq

This did a correct install -- but of an older version of 2.2.0. Ok, so I have something better than nothing, I suppose.

Why does it have to be so damn hard ... grrrrr ... .

Solution 4:

Consider using easy_install, perhaps in connection with a Python virtual environment. You need to install the libzmq-dev package so that the Python package compiles.

sudo apt-get install libzmq-dev
virtualenv ~/test-ve
source ~/test-ve/bin/activate
easy_install pyzmq

Note the absence of sudo for the easy_install call, this is due to the Python virtual environment. You need to activate the virtualenv before running the Python code, though. For systemwide installation, simply do

sudo apt-get install libzmq-dev
sudo easy_install pyzmq

Solution 5:

Why not try the later libzmq3 lib + dev tools:

sudo apt-get install --reinstall libzmq3 libzmq3-dev
