[Bug]: "Python kernel with Poetry" example fails to build

[emeinhardt]

Current Behavior

I have followed the documented example here and poetry fails when attempting to generate a lock file.

Expected Behavior

The tutorial example should work out of the box.

Steps To Reproduce

1. Bootstrap the process via nix-shell -p poetry (cf 320)

mkdir my-project
cd my-project
nix flake init --template github:tweag/jupyenv

3. Confirm nix run succeeds without issue.

4. mkdir my-custom-python && cd my-custom-python

5. <copy/paste the example 'pyproject.toml'>

6. Attempt to lock the poetry file:

> poetry lock
Creating virtualenv jupyter-nix-kernel-ipython-oxr5bDaL-py3.10 in /home/emeinhardt/.cache/pypoetry/virtualenvs
Updating dependencies
Resolving dependencies... (0.1s)

Failed to create the collection: Failed to execute program org.freedesktop.secrets: No such file or directory.

OS

system: "x86_64-linux", multi-user?: yes, version: nix-env (Nix) 2.11.1, channels(emeinhardt): "", channels(root): "home-manager-22.11.tar.gz, nixos-22.11, nixos-hardware", nixpkgs: /nix/var/nix/profiles/per-user/root/channels/nixos

Version

3ad2c95

Additional Context

The fix/hack in poetry/1917 works:

<continuing from 6 above>
6.

> export PYTHON_KEYRING_BACKEND=keyring.backends.null.Keyring
> poetry lock
Updating dependencies
Resolving dependencies... (5.2s)

Writing lock file

7. Update kernels.nix:

{pkgs, ...}: {
  kernel.python.minimal = {
    enable = true;
  };
  kernel.python.python-with-numpy = {
    enable = true;
    projectDir = ./my-custom-python;
  };
}

8. cd .. && nix run then also fails:

> cd ..
> nix run

...but this is fixable by removing hatchling = "^1.3.1" from pyproject.toml.

Relevant log output

No response

...but this is fixable by removing hatchling = "^1.3.1" from pyproject.toml.

This doesn't fix it for me, as it later complains about > ModuleNotFoundError: No module named 'hatchling'

[pachiras]

Removing 'hatchling' didn't help.
Nix still demands 'flit_core'.
