Plugin fails to install poetry (missing python3)

[chris-lingwood-korelabs-co]

Starting with a blank debian:trixie container and the .mise.toml file

[tools]
poetry = {version='2.2.1', pyproject='pyproject.toml'}
python = '3.12.9'

I also tried it without pyproject being defined and it didn't seem to help.

Run something like this to get mise installed:

apt-get update &&\
apt-get install -y \
curl \
git \
gnupg2 &&\
apt-get clean &&\
curl -Lo - https://mise.jdx.dev/gpg-key.pub | gpg --dearmor | tee /usr/share/keyrings/mise-archive-keyring.gpg 1> /dev/null &&\
echo "deb [signed-by=/usr/share/keyrings/mise-archive-keyring.gpg arch=amd64] https://mise.jdx.dev/deb stable main" | tee /etc/apt/sources.list.d/mise.list &&\
apt-get update &&\
apt-get install mise

Or whatever approach get's you mise that you like.

Then run the following (I've always had trouble getting python and poetry to install in the same command).

mise trust -y
mise install python
mise install poetry

Python installs ok.
Poetry does not.

If you try and fix the PATH manually it does help but I can't fathom what this error actually is.

# Welcome to Poetry!

This will download and install the latest version of Poetry,
a dependency and package manager for Python.

It will add the `poetry` command to Poetry's bin directory, located at:

/root/.local/share/mise/installs/poetry/2.2.1/bin

You can uninstall at any time by executing this script with the --uninstall option,
and these changes will be reverted.

Not sure if this is two bugs or both are the same bug or that I'm missing something key. Now, to be fair mise isn't activated, but that shouldn't matter to mise internally should it?

I ran into what might be a related issue

When using the pyproject option with poetry listed before python in my mise.toml:

[tools]
poetry = { version="latest", pyproject="pyproject.toml" }
python = "3.13"

Mise would hang indefinitely on invocation. After some debugging with MISE_TRACE=1, the trace stopped at:

DEBUG [vfox:poetry] env_keys

Looking at env_keys.lua, I noticed this function that calls mise which python3:

local function get_mise_python_path_prefix()
    local handle = io.popen("mise which python3 2>/dev/null")
    -- ...
end

My guess is that calling mise which from within a mise hook might cause some kind of circular dependency, though I'm not entirely sure of the internals.

Changing the order so python is listed before poetry resolved the hang:

[tools]
python = "3.13"
poetry = { version="latest", pyproject="pyproject.toml" }

Can confirm the above hanging bug as well, just hit it, workaround works! Thanks for that! Looks like an infinite recursion for some reason. Github actions does not care for this! To give you a flavour:

Those numbers can get pretty big if you let it just sit there.

I tried the same fix for the original issue and it hasn't helped.

I was running into the same, what helped for me was mise uninstall python --all. Afterwards installing poetry worked.
