importlib_metadata is conflicting with pbr

[Jochman]

importlib_metadata pack is removed from pbr in the last release.

but if it is available to import, pbr is still using it. The problem occurs when an old version (like importlib_metadata==0.23) is presented and it is not compatible with the implementation in PBR.

I don't understand this. We didn't remove anything from pbr.

Could you give us an example of the kind of errors you are seeing?

[Jochman (jochman)]

In the latest releases you've added the check for if importlib_metadata is installed.

Error I got:
