pyzmq: Unable to make pyzmq work on pypy 5.1.1 32 bit on Windows

Error on use of pyzmq-15.3.0.dev0

When importing pyzmq, compilation claims that “sys/un.h” doesn’t exist although there shouldn’t be such “sys/un.h” because of Windows.

Environment

Note

I’ve not tried http://zeromq.org/docs:windows-installations because I don’t have idea how to build libzmq\builds\msvc\vs2008\libzmq.sln without Visual Studio. (32 bit version of VCBuild.exe doesn’t seem to be included in VC++ for Python 27 so it is impossible to complete C:\Windows\Microsoft.NET\Framework\v3.5\MSBuild.exe libzmq\builds\msvc\vs2008\libzmq.sln.)

I ran into this issue under 64-bit Windows 10 when running jupyter notebook with Anaconda 4.3.1. However, pip uninstall pyzmq and pip install pyzmq did the work for me, even though pip warned me that

DEPRECATION: Uninstalling a distutils installed project (pyzmq) has been deprecated and will be removed in a future version. This is due to the fact that uninstalling a distutils project will only partially uninstall the project.

I’m also experiencing this issue under OSX 10.11.4. This seems to be an issue with pyzmq’s bundled libzmq combined with pypy. Steps:

-pypy 5.4.1 via brew brew install pypy -pyzmq via pypy -m pip install pyzmq

I then get the same error as @alec-djinn

As a workaround if you install zeromq standalone (e.g. via brew) pyzmq no longer relies on its bundled libzmq, and all is right with the world. So:

-pypy -m pip uninstall pyzmq -brew install zeromq -pypy -m pip install pyzmq

I was facing the same issue when opening jupyter notebook:

The pip install/uninstall pyzmq did not work for me. Running conda install jupyter resolved the issue (note all of these steps were performed while in a conda virtual environment).

I can import zmq on win 10 ,anaconda Python 3.7. However when i try to make it part of an executable via pyinstaller i get the exact same issue about missing sys/un.h. pip install/uninstall pyzmq does not help me in this case. Had anybody success with @sakurai-youhei´s fix? To me it leads to a new error:

"c:\programdata\anaconda3\lib\site-packages\zmq\backend\cffi\__pycache__\_cffi_ext.c(267):
'zmq.h': not found!"

@Johannes0Horn Did you find the solution for the issue you mentioned? I am having the same issue right now. The pyinstaller cannot work with pyzmq even if I downgrade the pyzmq version.

Because Python 2.7 is no longer supported, I have checked this with pypy3 again.

Windows: 10.0.18363 pypy3: https://bitbucket.org/pypy/pypy/downloads/pypy3.6-v7.3.0-win32.zip pyzmq: pyzmq-19.0.0

And, I’d say nothing seems to have been changed so far; cl.exe reports C1083 due to missing sys/un.h.

This is still an issue (Windows 10, 64-bit Anaconda downloaded on 2018-11-15).

Workaround proposed by @LauriListak solved the issue.
