Failed to install Pyrobuf / ERROR: Failed building wheel for Pyrobuf with Python

[bespardon]

Could you please give me some ideas how to install package?
I have Mac OS Big Sur 11.2

When I make pip install Pyrobuf in terminal I get an error

Cython is installed correctly.

I need Pyrobuf to use the Pyrosm library
