The self.version used in Version._cmp is a List in LooseVersion's implementation, a Tuple in StrictVersion's implementation. Attempting to compare Strict & Loose versions results in a TypeError.

I'd like to PR a fix, but I'd like to know if I'm being stupid first :)

Hello!  Are you seeing this problem when building or installing some package, or are you using the classes directly?

If it’s the latter, I would recommand you to use https://pypi.org/project/packaging/ rather than distutils, which is not meant to be used as a generic library.

I'm using these classes directly to parse semantic-ish versions in metadata
for Munki packages (a package manager for MacOS). Looks like this packaging
library is what I should use. Thanks you!
