This is likely due to the sdist including pre-cythonized c files generated with a version of cython that is too old to support newer versions of python.

If you install directly from the repo does it work?

May be a moot point, but we should make cython an install-time dependency and not bundle the c files (to make it more forward compatible).

Thank you and for your time.

I did not use repo due to the network conditions.

I modified the source code according to the prompt, completed the compilation, and installed successfully.

Of course, I agree with you.

Thank you very much! @tacaswell

I close this issue, since the precompiled _geoslib.c file has been removed from the repository and cython has been added as a setup requirement. For Python 3.8 under Ubuntu 20.04 you can also try the preliminary precompiled wheels that I uploaded to PyPI, which come with its own copy og libgeos_c.
