Install a library for all the virtualenvs

[lcfd]

Hi!

I'm trying to use pynvim to add Python support to Nvim. So I need this package always available.

So I installed the library:
PIP_REQUIRE_VIRTUALENV=false pip install pynvim

The package is available when I'm not in a Poetry venv:
/Users/xxx/.asdf/installs/python/3.10.6/lib/python3.10/site-packages/pynvim/__init__.py

When I'm in a Poetry environment pynvim is not available anymore.

I tried using this configuration:
poetry config virtualenvs.options.system-site-packages true

But the package is still not available. And it doesn't show up in the poetry show list.

Any idea about what I should do?

You want neovim to always use the same virtual environment, regardless of the virtual environment it is within, in my experience. To do so, you should create a virtual environment to install pynvim in:

python3 -m venv ~/.config/nvim/venv
~/.config/nvim/venv/bin/pip install pynvim

And then configure Vim to always use it:

let g:python3_host_prog = "~/.config/nvim/venv/bin/python3"

I'm a little rusty on specifics, but hopefully that puts you on the right track.

Hi! Absolutely! Thank you for the suggestion.

I am a little surprised that I am the first that needs such a thing.
Let's see if anyone else has any other ideas.

So Neovim a part, it's not possible to use a global package alongside Poetry?

If you want something in your Poetry environment, it needs to be in pyproject.toml. Poetry does not have a feature where it installs packages globally -- such would be counter to the goal of consistent and reproducible installations.

Sure, at the moment your solution should be enough.
