Nice!

A bit of an issue I have:

django-redis {'hashes': ['sha256:af0b393864e91228dd30d8c85b5c44d670b5524cb161b7f9e41acc98b6e5ace7', 'sha256:f46115577063d00a890867c6964ba096057f07cb756e78e0503b89cd18e4e083'], 'index': 'pypi', 'version': '==4.10.0'}
django-webpack-loader {'editable': True, 'git': 'https://github.com/peergradeio/django-webpack-loader', 'ref': '72065565dc57ad7e7a19a8d933eeb2feb5f17195'}
Traceback (most recent call last):

@tony I recommend to try dephell instead: https://github.com/dephell/dephell

It will do the same thing.

@sobolevn : Thank you!

So it'll be able to convert Pipfile to poetry's pyproject.toml ?

Would it require everyone on the team installing dephell, or just poetry?

You can convert your Pipfile once. And then use just poetry.

dephell deps convert --from=Pipfile --to-format poetry --to-path pyproject.toml

And then you have a valid poetry file 👍
