python-poetry depends on an uncompatible version of python-tomlkit

morgoth_bauglir · 2020-04-27 01:19:19

The package python-poetry depends on python-tomlkit, but with a version constraint:

Traceback (most recent call last):
  File "/usr/lib/python3.8/site-packages/pkg_resources/__init__.py", line 584, in _build_master
    ws.require(__requires__)
  File "/usr/lib/python3.8/site-packages/pkg_resources/__init__.py", line 901, in require
    needed = self.resolve(parse_requirements(requirements))
  File "/usr/lib/python3.8/site-packages/pkg_resources/__init__.py", line 792, in resolve
    raise VersionConflict(dist, req).with_context(dependent_req)
pkg_resources.ContextualVersionConflict: (tomlkit 0.6.0 (/usr/lib/python3.8/site-packages), Requirement.parse('tomlkit<0.6.0,>=0.5.11'), {'poetry'})

During handling of the above exception, another exception occurred:

    raise DistributionNotFound(req, requirers)
pkg_resources.DistributionNotFound: The 'tomlkit<0.6.0,>=0.5.11' distribution was not found and is required by poetry

python-tomlkit was updated to 0.6.0, which renders python-poetry unusable.

I can confirm this - it does seem to be a packaging bug, you could raise it on the bug tracker.

Ugh, why is this project so flaky with versions?

I don't see any upstream suggestion that they're considering bumping the version...

Instead of running `poetry <cmd>` you can run `python -m poetry <cmd>` to short-circuit the version check. Do you run into any actual issues with the new tomlkit version, other than the dependency constraint? If not, we can just patch out the version pinning...

(Note that I think it should be fine because the only real change was https://github.com/sdispater/tomlkit/co … da955e10a2.)

I only use tomlkit indirectly in the context of python-poetry, so can't comment on that.

I agree!

I'm pretty sure he was asking whether using python-poetry the way he suggested works suitably. That invocation allows it to run without the version check, but does it result in incorrect results?

Yep, misunderstood that. Let me try again:

I confirm: t works just fine running `python -m poetry <cmd>` instead of `poetry <cmd>.

Fix uploaded, get it with the following command (will succeed once your mirror has the package, usually within an hour or two):

pacman -Syu 'python-poetry>=1.0.5-2'
