Hey! Whats going on with ipympl?
I've encountered a problem with the ipympl library.

First I added ipympl as a dependency:

poetry add ipympl
Using version ^0.9.4 for ipympl

Then, when I tried to enter the development environment with the command nix develop I received the following message:

nix develop

       > ModuleNotFoundError: No module named 'hatchling'

I tried to override ipympl:

myapp = mkPoetryApplication {
    projectDir = self;
    overrides = withDefaults (final: prev: {
        ipympl = prev.ipympl.overridePythonAttrs (old: {
            nativeBuildInputs = old.nativeBuildInputs or [ ] ++ [ final.hatchling ];
        });
    });
};

But it was unsuccessful:

I found https://github.com/tweag/jupyenv/blob/0c86802aaa3ffd3e48c6f0e7403031c9168a8be2/lib/overrides.nix#L34C74-L34C95 that there is a hatch-jupyter-builder.

This led to the following error:
ValueError: Aborting. Could not find cmd (jlpm) in path. If command is not expected to be in user's path, use an absolute path.

It's really weird!

I ended up with this config:

myapp = mkPoetryApplication {
            projectDir = self;
            overrides = withDefaults (final: prev: {
              ipympl = prev.ipympl.overridePythonAttrs (old: {
                  nativeBuildInputs = old.nativeBuildInputs or [ ] ++ [
                  final.hatchling
                  final.hatch-jupyter-builder
                  final.jupyterlab
                  pkgs.nodejs
                ];
              });

            });
          };

And I've got a crazy error message:

Try adding preBuild = "export HOME=$(mktemp -d)"

It seems that ipympl was installed successfully.
Thank you!

But it was really complicated

Hey! I tried to override cargoDeps of rpds-py package to support 0.19.1 version.
I have the following code:

myapp = mkPoetryApplication { 
            projectDir = self; 
            overrides = p2nix.overrides.withDefaults (final: prev: {
              rpds-py = prev.rpds-py.overridePythonAttrs (old: 
                lib.optionalAttrs (old.version == "0.19.1") ( lib.warn "version == 0.19.1" {
                  cargoDeps = lib.warn "override cargoDeps" (pkgs.rustPlatform.fetchCargoTarball {
                    inherit (old) src;
                    name = "${old.pname}-${old.version}";
                    hash = lib.warn "new hash was used in cargoDeps" "sha256-qIXdoCEVGCGUnTicZp4bUTJyGpFy9dwWY03lXUbxiHg=";
                  });

                  cargoFakeDeps = lib.warn "override cargoFakeDeps" (pkgs.rustPlatform.fetchCargoTarball {
                    inherit (old) src;
                    name = "${old.pname}-${old.version}";
                    hash = lib.warn "new hash was used in cargoFakeDeps" "sha256-qIXdoCEVGCGUnTicZp4bUTJyGpFy9dwWY03lXUbxiHg=";
                  });
                })
              );
            });
          };

I see that cargoFakeDeps was evaluated but cargoDeps wasn't.
This is the log output I received:

I found problem.
My overlay was overwritten by default:

withDefaults = overlay: [

      self.defaultPoetryOverrides
    ];

Hi all. Is there a best practice I'm missing for providing poetry itself in a dev shell? I've been using (slightly customised) versions of pkgs.poetry as a buildInputs / packages entry, but was wondering if poetry2nix exposes its version cleverly maybe.

(Motivation: I find this is needed to do poetry lock --no-update or poetry add foo --lock etc etc, and obviously don't want to use a global poetry version)

Hello,

I am trying to convert a project with poetry2nix.
The project has a web server launch via a gunicorn with Popen.

I have errors related to the fact that gunircorn could not import library such as filtetype.

It is working with the dev environment, what am I doing wrong ?

Hello,

I am trying to convert a project with poetry2nix.
The project has a web server launch via a gunicorn with Popen.
The webserver configuration is under website/web where scripts are in bin and the main library is under lookyloo.

I have errors related to the fact that gunircorn could not import library such as filtetype.

Hello,

I am trying to convert a project with poetry2nix.
The project has a web server launch via a gunicorn with Popen.
The webserver configuration is under website/web where scripts are in bin and the main library is under lookyloo.

I have errors related to the fact that gunircorn could not import library such as filtetype.

It is working with the dev environment.
Can you help me to find out what I am doing wrong ?

Answering my own question a bit, it seems like the example does do exactly that:

To be honest I saw it, but I am not sure hot to leverage it in my case.

Gunicorn is ran through a python script calling Popen.
