PyZMQ: Python bindings for 0MQ

This package contains Python bindings for 0QM. 0MQ is a lightweight and fast messaging implementation.

Building and installation


To build and install this Python package, you will first need to build and install the latest development version of 0MQ itself. After you have done this, follow these steps:

First, copy the setup.cfg.template file in this directory to setup.cfg and edit the include_dirs and library_dirs fields of the setup.cfg file to point to the directories that contain the library and header file for your 0MQ installation.

Second, run this command:

$ python install

Cython is not required to build pyzmq, but it is required if you want to develop pyzmq.


Generally you'll need to add the location of libzmq.dll to your $PATH. Here's Microsoft's docs: on this topic.

It is best to compile both ØMQ and PyØMQ with Microsoft Visual Studio 2008 or above. You should not need to use mingw.


On Linux, you will need to do one of the following:

  • Set LD_LIBRARY_PATH to point to the lib directory of 0MQ.

  • Build the extension using the -rpath flag:

    $ python build_ext --rpath=/opt/zeromq-dev/lib --inplace


To develop PyZMQ, you will need to install Cython, version 0.13 or greater. After installing Cython, instead of doing python install do:

$ python build_ext --inplace
$ python develop

This will build the C extension inplace and then put this directory on your sys.path. With this configuration you only have to run:

$ python build_ext --inplace

each time you change the .pyx files. To clean the sources, you can do:

$ python clean


To run the test suite after installing, just do:

$ python test
