`assert term is not None` in poetry lock/update

Poetry version:
Python version:
OS version and name:
pyproject.toml:

[x] I am on the latest stable Poetry version, installed using a recommended method.
[x] I have searched the issues of this repo and believe that this is not a duplicate.

Issue

I do poetry update and I get the following error (using internal libraries, so can't share the toml):

what does this mean?

this is the partial toml (removed some internal libraries):

if you can't share a pyproject.toml that reproduces this there's little chance that you can be helped

it probably has something to do with an unusual version number somewhere in your tree - a release candidate or a dev version or whatever.

But if you're unable or unwilling to enable anyone else to reproduce this, you're likely on your own - sorry.

dimbleby commented 1 year ago

also we probably might as well assume it's a duplicate of #8202

python-poetry / poetry

`assert term is not None` in poetry lock/update #8405
