Fix OverrideNeededError

in Poetry

Solution

The "OverrideNeededError" in Poetry usually arises from dependency conflicts during resolution, particularly when a dependency specifies incompatible version constraints or markers for different Python versions. To resolve this, carefully review your pyproject.toml for version constraints and environment markers in dependencies, ensuring they're compatible across your project's supported Python versions. If necessary, use conditional dependencies or environment markers to specify different versions based on the Python environment, like `python = ">=3.10,<3.12"` to address issues such as Python 3.12 compatibility.
