Issue

I would like to use poetry. It took me waaaaay to long to find this issue:
#663
It's closed but has nuggets with wisdom for how to import from other package managers.

Please, Please, include at least this issue in the documentation.

There is a tool that supports migrating: https://dephell.org/docs/cmd-deps-convert.html

It would be better to have some commands like poetry migrate ./requirements.txt or poetry migrate --pipenv ./Pipfile. I don't want to install another tool.
Oh sorry I didn't read #663 .

Here's an example how to convert a "realworld app" from pipenv to poetry: teamniteo/pyramid-realworld-example-app#84

It should definitely be in the documentation, and maybe in the "get started" doc.

As a "work around" until some sort of capability comes about, you can try something like this: https://stackoverflow.com/a/62787881/2009612

cat requirements.txt | xargs poetry add

[sinoroc]

Use dephell deps convert: https://dephell.readthedocs.io/cmd-deps-convert.html

There is also https://pypi.org/project/pipenv-poetry-migrate/

@rvanlaar error I get with dephell

 dephell deps convert --from-format=pipenv --to-format=poetr
y
usage: dephell deps convert [OPTIONS]
dephell deps convert: error: argument --from-format: invalid choice: 'pipenv' (choose from 'conda', 'egginfo', 'flit', 'imports', 

'installed', 'pip', 'pipfile', 'pipfilelock', 'piplock', 'poetry', 'poetrylock', 'pyproject', 'sdist', 'setuppy', 'wheel')

Have a look at example 5. It shows what you need. https://dephell.readthedocs.io/cmd-deps-convert.html#more-examples

@rvanlaar thanks, do you know why is it saying this now:

dephell deps convert --from-format=pipfilelock --from-path=Pipfile.lock --to-format=poetrylock --to-path=poetry.lock

WARNING cannot find tool.dephell section in the config (path=pyproject.toml)
ERROR InvalidSpecifier: ==not in3.0

how do I use pipenv.lock?

[rvanlaar]

I would ask for support at the dephell project. I'm a long time poetry user and haven't had to use the conversion tools in quite some time.

@rvanlaar no problem thanks, the project dephell is archived now btw

I 2nd this. I like to use cookiecutter a lot, as well as poetry. Unfortunately a lot of the cookiecutter python projects are requirements/setup.py-based.

There is an export command, so would it seem reasonable to include a poetry import command that creates the project from a setup file (if it exists) and a list of requirements.txts?

[src-r-r]

And I got a little too impatient, so I created this Python tool to do just this (called stanza...get it?). Parses requirements.txt files and automatically names and versions your project. It even allows for referenced requirements "e.g. -r ..."

I created it in a rush (but still tested it), so contributions welcome!

I should note that dephell is now archived, domain taken over by squatters, and therefore dead. Other solutions should be used.
