error during installation

[JeremyB]

Hello

  I tried to install Owlready2 (version 0.22) on windows10 but I got the following error : TypeError: stat: path should be string, bytes, os.PathLike or integer, not NoneType

  I already tried installation using a local archive or a previous version of Owlready2 (version 0.21), both using pip or pip3.

  Any insight would be appreciated.

ps : python version 3.7.3

Hi,

Do you have a complete traceback with the error? I would like to know which path is causing problem.

Another question: do you have Cython installed? If Cython is installed, Owlready setup will build the C optimized module, but it requires a working C compiler. If Cython is not installed,  this module is not built and thus the installation is simpler.

I manually installed Owlready2 without problem. It seems I can still get the same error using "pip install Owlready2", you'll find the complete traceback below.

I do have Cython installed: version 0.29.14 but I'm not sure for the C compiler, I'll check.

Hi,

It seems that the problem is related to the runtime redistributable files for MS Visual C++ (VCRuntimeRedist), but I am unable to tell more.

I've improved Owlready2 setup.py, so as if Cython installation fails for any reason, it will try a non-Cython installation (thus not requiring the C compiler).
