macOS idem install does not copy to '~/.idemenv/bin' dir + errors in [14269] Failed to execute script 'idem' due to unhandled exception!

[TheBigBear]

The idem install latest followed by idem use latest does not create a ~/.idemenv/bin dir nor does it copy the specified idem binary there.

So I have tried duplicating the output of idem exec test.version that is shown on the github page by instead entering the direct path to the binary in ~/.idemenv/versions but that does not like the command either?

Typing gives me:

~/.idemenv/versions/idem-v18.10.3 exec test.version

AttributeError: version
[14269] Failed to execute script 'idem' due to unhandled exception!

I recognise the various lines of WARNING: file already exists but should not: as something akin to the upstream idem issues
on the vmware idem gitlab repo.
On macOS https://gitlab.com/vmware/idem/idem/-/issues/46
On linux https://gitlab.com/vmware/idem/idem/-/issues/43
On windows https://gitlab.com/vmware/idem/idem/-/issues/45

But the rest of the unhandled expecption looks different to me.
