You need not to build on windows, install prebuilt binaries from PYPI.

I wrote I can't install with pip. I got the error. And I don't know why it shows that there is no pybind11 when it is installed. What a version of python is required?

@Allamaris0

What is the python version you are using?
What version of windows you are using?

Windows 10, Python 3.8. You wrote somewhere that Python 3.9 is required.
