setuptools and setuptools_scm incompatible while executing python3 setup.py build

[rioter1]

After executing python3 setup.py build i get

[100%] Built target pysfm
/usr/local/lib/python3.8/dist-packages/setuptools_scm/_integration/setuptools.py:31: RuntimeWarning:
ERROR: setuptools==45.2.0 is used in combination with setuptools_scm>=8.x

Your build configuration is incomplete and previously worked by accident!
setuptools_scm requires setuptools>=61

Suggested workaround if applicable:

• migrating from the deprecated setup_requires mechanism to pep517/518
  and using a pyproject.toml to declare build dependencies
  which are reliably pre-installed before running the build tools

AND
after executing python3 setup.py build_doc I get

Theme error:

Anyone know how to solve it? i tried upgrading setuptools and setuptools_scm but that didn't solve the problem.
