Have ty recognize the .venv packages in a subdirectory

[jooelerich]

Hi, I'm not sure if this is a bug or something else is misconfigured. I have a project, where the .venv and pyproject.toml is in a subdirectory (monorepo, all python related stuff resides in backend/.) The project interpreter is set to uv and correctly points to the backend/.venv). All interpreter paths are correctly set and with stock pycharm, everything works as intended.

ty/Ruff, both with the native language server and LSP4J fail to resolve imported packages from the virtual environment. How can I resolve that?

Thank you for your work!

/e: In the LSP log it reports the wrong python version, so I guess the issue is, that the LSP Server is started in the project root and is not aware of the .venv:

Putting a ty.toml with the following content into the project root resolves the issue:

[environment]
python = "./backend/.venv"
