error installation GR python

[halim hamadi]

I want to install GR plot in python using pip, but I receive an error when installing GR.

Collecting gr
  Using cached gr-0.16.0.tar.gz
    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):
      File "<string>", line 20, in <module>
      File "C:\Users\HALIMH~1\AppData\Local\Temp\pip-build-vhpiefs2\gr\setup.py", line 200, in <module>
        class check_ext(Command, build_static):
    TypeError: Cannot create a consistent method resolution
    order (MRO) for bases build_static, Command

Can anyone help please?

Thank you.
