There is no wheel with compiled libraries for Python 3.8

[nevmerzhitsky]

What language does this apply to?

Python 3.8

Describe the problem you are trying to solve.

The wheels on PyPI doesn't have google/protobuf/pyext/_message.???.so file if I install the package with pip of Python 3.8. In this case pip use protobuf-X.Y.Z-py2.py3-none-any.whl. Thus python module google.protobuf.pyext.cpp_message is broken to import. In fact, I don't use the latter, but I need to import classes from google.protobuf.pyext._message (sorry).

Describe the solution you'd like

We need wheels with compiled libraries for Python 3.8.

Describe alternatives you've considered

Downgrade my project to 3.7.

Duplicate of #6214, unfortunately this issue has been brought up 6 months ago during the first beta release of Python3.8, and even after 3 releases of protobuf done since then, this is still not fixed in the latest version (3.11 deployed on Nov. 26).

It works now with version 3.11.2. Thanks a lot!

Thanks!

I've tested it with a docker image python:3.8:

cd /usr/local/lib/python3.8/site-packages/
pip install protobuf
cd google/protobuf/pyext/
ls -la
