## TL;DR

If dg dev cannot find the venv for a project inside a uv workspace, create a.env file in the project directory with DG_PROJECT_PYTHON_EXECUTABLE set to the shared venv's python binary (for example workspace_1/.venv/bin/python), using plain KEY [your value] or export KEY [your value] syntax.

## Steps

1. If dg dev cannot find the venv for a project inside a uv workspace, create a .env file in the project directory with DG_PROJECT_PYTHON_EXECUTABLE set to the shared venv's python binary (for example workspace_1/.venv/bin/python), using plain KEY [your value] or export KEY [your value] syntax. That is the supported escape hatch the maintainers point at while uv-workspace auto-detection is still unplanned. Do not symlink .venv: it does not work with Pixi or Conda style environments.

## When to use

You are seeing this: That is the supported escape hatch the maintainers point at while uv-workspace auto-detection is still unplanned. Use this skill when you run into "dg dev with uv workspaces: point DG_PROJECT_PYTHON_EXECUTABLE at the shared venv".

## When not to use

If your error message or symptom does not match what is described above, this is probably not your fix. Search for your exact error text instead of forcing this one to fit.

## Versions

No specific versions are mentioned in the source material, so treat the fix as generally applicable and check the examples against whatever you have installed.

## Why this happens

The original report does not dig into a root cause. It documents the symptom and the fix that resolved it.
