You've checked the box to declare that you included output with -vvv, but you haven't done so.

The RECORDS file in the swat wheel contains nonsense hashes. Please report this to that project - https://github.com/sassoftware/python-swat/.

If you're feeling keen, please also report to https://github.com/pypa/installer/ that it would be nice if they handled this more gracefully

Edit: I reported to installer, which is the way eventually to get this to be handled gracefully. You should still report to swat that their wheel is invalid.

Closing this issue as the external issue has been resolved and swat@1.13.1 is installable. No real action on Poetry side. Maybe improvement on error handling here - happy to review PRs submitted to this effect.

Relevant code that installs the wheel is at

poetry/src/poetry/installation/wheel_installer.py

Lines 88 to 116 in 9b3893a

	def install(self, wheel: Path) -> None:
	with WheelFile.open(wheel) as source:
	try:
	# Content validation is temporarily disabled because of
	# pypa/installer's out of memory issues with big wheels. See
	# https://github.com/python-poetry/poetry/issues/7983
	source.validate_record(validate_contents=False)
	except _WheelFileValidationError as e:
	self.invalid_wheels[wheel] = e.issues
	scheme_dict = self._env.paths.copy()
	scheme_dict["headers"] = str(
	Path(scheme_dict["include"]) / source.distribution
	)
	destination = WheelDestination(
	scheme_dict,
	interpreter=str(self._env.python),
	script_kind=self._script_kind,
	bytecode_optimization_levels=self._bytecode_optimization_levels,

	destination=destination,
	# Additional metadata that is generated by the installation tool.
	additional_metadata={
	"INSTALLER": f"Poetry {__version__}".encode(),
	},
	)

The exception can be captured and handled here as well.
