Using CPython 3.14.2
Would create project environment at: .venv
  × No solution found when resolving dependencies for split (markers: python_full_version == '3.8.*'):
  ╰─▶ Because the requested Python version (>=3.7) does not satisfy Python>=3.9 and sphinx==7.4.7 depends on Python>=3.9, we can conclude that sphinx==7.4.7 cannot be used.
      And because only the following versions of sphinx are available:
          sphinx<=7.4.7
          sphinx>=8
      we can conclude that sphinx>=7.4.7,<8 cannot be used.
      And because gitpython[doc] depends on sphinx>=7.4.7,<8 and your project requires gitpython[doc], we can conclude that your project's requirements are unsatisfiable.

hint: While the active Python version is 3.14, the resolution failed for other Python versions supported by your project. Consider limiting your project's supported Python versions using `requires-python`.
hint: The `requires-python` value (>=3.7) includes Python versions that are not supported by your dependencies (e.g., sphinx==7.4.7 only supports >=3.9). Consider using a more restrictive `requires-python` value (like >=3.9).
