Use uv2nix to install ansible with additional python modules?

[johanneskastl]

Dear maintainers,

sorry for the newbie question, but due to lack of knowledge on the internals of uv, I might have just failed to understand how to use uv2nix.

Could this be used to install Ansible with additional python modules on NixOS?

I currently have an issue where Ansible from NixPkgs does not find python modules that are installed on the system. Thinks like the cryptography or kubernetes modules that are used by some of Ansible's modules (which are basically python).

If this can be done, are there examples of using uv2nix with home-manager? How would I get started?

Thanks in advance!

Kind Regards,
Johannes

I have the exact same use-case.

I would like to use uv2nix to install just a venv (a collection of versioned packages, but none of my own packages, so no build system) - this works fine with uv, but uv2nix appears to be forcing a build system currently. If there is a way to do this correctly (just build a venv, not a package), I haven't figured it out.

I'm also doing this for ansible.

You can simply add ansible to pyproject.toml as usual and only build ansible or whatever other relevant package for your venv using mkVirtualEnv:

mkVirtualEnv "ansible-env" {
  ansible = [ ];
}

For other more advanced cases there is the query API.
