I'm getting these errors while working with Spyder and Anaconda. My Python scripts only work with the Anaconda prompt and nothing else is working. This is the whole error:

_cffi_ext.c
anaconda3\lib\site-packages\zmq\backend\cffi\__pycache__\_cffi_ext.c(266): fatal error C1083: Cannot open include file: 'sys/un.h': No such file or directory

I even uninstalled and installed zmq but the error persists.

Try

pip uninstall pyzmq 
pip install pyzmq

@CanciuCostin's answer is correct, but for doing something slightly different worked:

pip uninstall pyzmq 
pip install --user pyzmq

HTH.
