Issue

I can't run poetry install. Is this issue with Pendulum or poetry version?

➜  pendulum git:(master) poetry install

  RuntimeError

  The Poetry configuration is invalid:
    - Additional properties are not allowed ('group' was unexpected)

Hmm... it could be issue on poetry python-poetry/poetry#4983

I ran into this and fixed it based on this comment pointing out that pendulum uses a preview version of poetry, so unless you specifically install that version, poetry won't work properly with pendulum's config.

So it's not so much a poetry issue as it is pendulum being a little eager to have those sweet new features. 😅

Hi @rileyjohngibbs thanks for the hint! It works now.

➜  pendulum git:(master) poetry install
Installing dependencies from lock file

No dependencies to install or update

Installing the current project: pendulum (3.0.0a0)

And the poetry version now:

➜  pendulum git:(master) poetry --version
Poetry (version 1.2.0a2)
