It used to just warn:

Do we consider this a regression or not ?
This used to just be a warning under older versions:

I think we consider it a bugfix. Is this python-poetry/poetry-core#461 meaning this has already changed in 1.2.x?
dimbleby commentedon Mar 28, 2023
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 onsfmqrb commentedon Mar 30, 2023
The exact same issue happened to me.
using version 1.1.13 there is no error and
poetry installwould be executed flawlessly.some information about my system env using
poetry debug infotrim21 commentedon Apr 10, 2023
I have the same error with
Could not parse version constraint:looks like
constrainthere 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 commentedon Apr 10, 2023
this is already fixed in poetry-core, this issue can be closed
trim21 commentedon Apr 10, 2023
No it's not. I just try poetry@main with poetry-core@main it still fail.
dimbleby commentedon Apr 10, 2023
that stack is quite different from the one reported in this issue, please raise new problems in new issues
(this issue can still be closed!)
