Could not parse version constraint #7729

clintonroy · 2023-03-28T11:06:49Z

Poetry version: 1.41
Python version: 3.11.2
OS version and name: Debian Testing
pyproject.toml: https://gist.github.com/clintonroy/867fe37398c9063a4ba0809b0dc1e9ef

I am on the latest stable Poetry version, installed using a recommended method.
I have searched the issues of this repo and believe that this is not a duplicate.
I have consulted the FAQ and blog for any relevant entries or release notes.
If an exception occurs when executing a command, I executed it again in debug mode (-vvv option) and have included the output below.

Issue

Do we consider this a regression or not ?

This used to just be a warning under older versions:

The text was updated successfully, but these errors were encountered:

radoering · 2023-03-28T15:22:05Z

I think we consider it a bugfix. Is this python-poetry/poetry-core#461 meaning this has already changed in 1.2.x?

dimbleby · 2023-03-28T18:27:19Z

maybe makes sense for the marker parsing to reraise this as InvalidMarker, which the code path shown in the call stack would then catch and warn on

The exact same issue happened to me.

trim21 · 2023-04-10T18:04:05Z

I have the same error with Could not parse version constraint:

looks like constraint here is empty string.

And I can't find a way to know which package this is.

Also I can't re-produce it in my computer, it only failed in windows ci...

dimbleby · 2023-04-10T18:46:30Z

this is already fixed in poetry-core, this issue can be closed

trim21 · 2023-04-10T19:15:36Z

No it's not. I just try poetry@main with poetry-core@main it still fail.
