Unfortunately, building the documentation requires Python 3.9+ since the backport for class properties is not lazily evaluated, unlike the modern implementation which uses @classmethod & @property instead.

jumpstarter/jumpstarter/backports.py

Lines 1 to 9 in c0cc0db

	class classproperty(property):
	def __get__(self, obj, objtype=None):
	return super().__get__(objtype)
	def __set__(self, obj, value):
	super().__set__(type(obj), value)
	def __delete__(self, obj):
	super().__delete__(type(obj))

ReadTheDocs doesn't support Python 3.9 as of yet. See readthedocs/readthedocs.org#7554.
