Yes, it no longer works as supplied. On installation it installs some packages which are incompatible and trying to resolve them would appear to not be possible.

I spent about 2 hours on this. I haven't yet come across a package manager that actually doesn't get into circular dependency hell. So the problem is that when you install it installs packages of later versions that it was originally built with, those then complain that others are not compatible, so you might think you just update those, but you can't because the later ones remove things it relied on. If you just keep trying to satistfy the dependencies it still won't run because it then needs something that is depricated. So you cannot resolve it with dependencies unless you have encyclopedic knowledge of everything it uses. Since you cannot know this, it cannot be resolved.

The installer package should have had fixed requirements.txt since it didn't its now not possible to determine short of trying to work out the packages that were available on the date it used to work.
