(Disclaimer: I'm new to ORT so I hope my question is relevant)

Describe the bug

I have a Python project built using poetry 2.1.3 (installed using pip install poetry).
I want to analyze it using ORT 63.1.1
When I run ort it says:

Poetry failed to resolve dependencies for path 'poetry.lock': IOException: Running 'poetry export --without-hashes --format=requirements.txt --only=main' in '/home/mando/git/fuzzy-set' failed with exit code 1:
The requested command export does not exist

And indeed poetry export does not exist, see this message). What should I do?

To Reproduce

In my setup my source tree is in ~/git/fuzzy-set which contains the poetry.lock and pyproject.toml files.

Steps to reproduce the behavior:

pip install poetry -U
mkdir ~/ort/fuzzy-set/
ort analyze -i ~/git/fuzzy-set -o ~/ort/fuzzy-set/

... and the error shows.

Expected behavior

I guess that ORT should cope with the various versions of poetry or at least guide the user to configure ~/.ort/config.yml if this can help.

Console / log output

(mando@velvet) (~) $ ort analyze -i ~/git/fuzzy-set -o ~/ort/fuzzy-set/
Hoplite is configured to infer which sealed type to choose by inspecting the config values at runtime. This behaviour is now deprecated in favour of explicitly specifying the type through a discriminator field. In 3.0 this new behavior will become the default. To enable this behavior now (and disable this warning), invoke withExplicitSealedTypes() on the ConfigLoaderBuilder.

And indeed poetry export does not exist, see this message). What should I do?

Google for the error and find that the plugin needs to be installed separately as of Poetry 2.0 😉

BTW, I find the plugin docs quite misleading, the name of the plugin should be written as poetry-plugin-<name>, so use something like

$ pip install (--user) poetry-plugin-export

This all should not be necessary when using the Docker image for ORT that we provide, see

ort/Dockerfile

Line 177 in 44aabf8

poetry-plugin-export=="$PYTHON_POETRY_PLUGIN_EXPORT_VERSION" \

If it was necessary, that would be a bug. However, it seems you're using ORT from its stand-alone binaries.

Hello,

Thank you @sschuberth.
Yes, I use the standalone binaries.
And indeed, your answer solved my problem. More precisely, I ran:

pip install poetry-plugin-export python-inspector

Besides, I believe that the ORT error message could be slight more user-friendly (hence we wouldn't have to dive in the documentation or search on the Internet):

Current message:

The requested command export does not exist.
Documentation: https://python-poetry.org/docs/cli/

Wished message:

The requested command export does not exist.

Ensure that poetry-plugin-export and python-inspector are installed:

Actually, that message does not come from ORT, but from Poetry itself. So it's not really under our control.

If you agree, I'd like to close this and probably move it to a discussion, as it's not really an issue in the sense of a bug or enhancement.

Yes, perfect. I thought is was possible to enrich the error message, but got it.
