> [ERROR] Unexpected argument: --target=I

pymanager install 3.12-32 --target=I:\kuankuan\Download\test-pym

Huh, oh wow, that's pretty terrible. I wonder what's going on here, we definitely run these as part of the regular build process...

At a guess, it might be a problem with both = and : being supported as a separator. Using --target "<path>" (that is, a space after the argument) likely works fine.
