Hello,

I have a working pyproject.toml used by other package management tool, but it is not compatible with uv.
During CICD, I want to use uv to create a .venv, and manually install some packages.

I used:

- name: Install uv
  uses: astral-sh/setup-uv@v8.0.0
  with:
    enable-cache: true
    activate-environment: true

This raises an error, saying that uv cannot parse some special syntax in pyproject.toml, which is expected.

I can reproduce the same error local with uv venv .venv.

However, I can bypass it locally with uv venv .venv --no-project, but I haven't found an equivalent param in astral-sh/setup-uv.
Did I miss it, or is it not supported ?

There's no env var for this locally either, I must use inline param --no-project. If uv supports an env var, then I can use it in both locally and in CICD

I know I can set the param activate-environment: false to use system level environement, but for my specific use case, I need an venv in CICD.
