error: metadata-generation-failed

I can't see any option in pyproject.toml that tells it the module is actually called 'hypercorn' not 'nonecorn'; suspect there's something missing but not sure

Start by inspecting pyproject.toml and reproducing the failure with the provided sdist installation command in a fresh virtual environment. The work is done when the source distribution can generate metadata and install successfully without the ModuleOrPackageNotFound error.
