that's my mistake... sorry about that! I fixed the installation issue for py-backports.weakref in ​this commit, and intended to remove the py35/py36 subports as they are not needed since the functionality is introduced in Python 3.4. Instead I moved them to py-graveyard and now they are set to be replaced_by py37-backports.weakref, which (correctly) does not exist. I'll attempt to correct this later tonight!

Either way, I assume you have this installed because of py36-tensorflow? If so, as a workaround for now you can do a port upgrade py36-tensorflow first and then you can uninstall py36-backports.weakref.

Renee,

Thanks for the quick response. The only people who do not make mistakes are dead. No penalty. No foul... :-)

Onwards,

Thanks for your prompt response Renee. I tried your workaround but I get an error when upgrading py36-tensorflow:

Should I file another bug report?

I am not sure whether this is related to the py-backports.weakref issue in this ticket... I opened ​a PR a few days ago to resolve this specific problem. I would suggest to try again once someone has merged that PR (after doing port clean --all py36-tensorboard py36-tensorflow) and see if that helps. If not, it appears to be a different problem and then you can certainly open another ticket.

In 1dc8f2a6e2ddc0ff6a35d5ba3734c91a82ff5889/macports-ports (master):

py-backports.weakref: remove py34/py35/py36 from py-graveyard

I moved them incorrectly to py-graveyard, which set them to be
replaced_by py37-backports.weakref

Closes: #58038
