How to Override with Egg File

[zromick]

I'm struggling to figure out how to do this:
In dependencies, we have a common library in prod.

In our flow:

1. We remove pdm lock and .venv so these files can be completely clean.
2. To successfully run pdm install, we need PDM to skip looking at the prod version and get the dev version of this library (a local editable), and so we remove common, run the install, and then add it back in.

Goal: Avoid having to edit the .toml every time we want to create a new lock file / venv

[project]
name = "app"
version = "0.0.1"
description = ""
authors = []
dependencies = [
    ...
    "common",
]
requires-python = "==3.13.*"
readme = "README.md"

[dependency-groups]
dev = [
    "-e file:///${PROJECT_ROOT}/../../common#egg=common",
    ...
]

Is there any way to avoid this?

I've been looking into this solution but don't know how it would be formatted:

Add this to your pyproject.toml:

[tool.pdm.resolution.overrides]
common = "file:///${PROJECT_ROOT}/../../common"

That tells the resolver to pull common from your local path instead of PyPI, so the "common" line in [project.dependencies] won't fail. ${PROJECT_ROOT} gets expanded the same way it does in your dev dependency group.

Your existing editable entry in [dependency-groups] dev still works alongside this. The override handles resolution, the editable entry handles how it's installed in dev. You won't need to touch the toml before pdm install anymore.
