Hi all, I am using poetry2nix and crane to build a polars expression in rust for use in python. The setup works outside nix, but I'm struggling to make it work with nix. Each part works fine, but as soon as I add the rust wheel to pyproject.toml, the build fails with:

error: path '/nix/store/msa2hjlaa5dplqcynlcfkjrfs6hv4kck-source/data_pipeline/ofd_expressions/target/wheels/ofd_expressions-0.1.0-cp311-abi3-linux_x86_64.whl' does not exist

My pyproject.toml looks like this (most stuff removed for clarity). Basically the rust code is in a subfolder ofd_expressions.

[tool.poetry.dependencies]
python = ">3.11.0,<3.12"
[...more packages...]
ofd_expressions = { file = "ofd_expressions/target/wheels/ofd_expressions-0.1.0-cp311-abi3-linux_x86_64.whl" }

    crateWheel =
      (craneLib.buildPackage (
        crateCfg
        // {
          pname = projectName;
          version = projectVersion;
          # cargoArtifacts = crateArtifacts;
        }
   # this points to the wheel that is built by crane
    crateWheelSrc = "${crateWheel}/${wheelName}";

    pkgOverrides = pkgs.poetry2nix.overrides.withDefaults (
      final: prev: {
        ofd_expressions = prev.ofd_expressions.overridePythonAttrs (old: {
         # neither of these seem to change the error message
          # src = crateWheelSrc;
          src = "${crateWheel}";
        });
      }
    );

    dagitApp = pkgs.poetry2nix.mkPoetryApplication {
      overrides = pkgOverrides;
      projectDir = ./.;
      preferWheels = true;

The override does not seem to have any effect, I get the same error whether I add it or not. What am I doing wrong?

I figured it out. The name is ofd_expressions, but the override must be named ofd-expressions Those were 8 hours well spent... :/

Hello, I'm trying to use P2N to get a development environment for Langchain https://github.com/langchain-ai/langchain.

I have a simple env:

myenv = { poetry2nix, lib }: poetry2nix.mkPoetryEnv {
          projectDir = self;
          preferWheels = true;
}
