poetry not compatible with precompiled python

[andersfylling]

Describe the bug When I tried setting up python and poetry for a project, the poetry install fails with:

/home/anders/.local/share/mise/installs/poetry/1.8.2/venv/bin/python3: error while loading shared libraries: /home/anders/.local/share/mise/installs/poetry/1.8.2/venv/bin/../lib/libpython3.10.so.1.0: cannot open shared object file: No such file or directory

Traceback:

  File "<stdin>", line 923, in main
  File "<stdin>", line 562, in run

To Reproduce

1. mkdir test && cd test
2. mise u python@3.10
3. mise u poetry

This led to the above error. I have never had poetry installed on this machine before, nor mise.

Expected behavior That poetry successfully installed.

precompiled pythons are not compatible with poetry. I don't know why but the issue needs to be fixed upstream since the issue is not with mise itself but the pythons mise uses. Here's how to disable precompiled pythons and reinstall:

mise settings set python_compile 1
mise install python -f

same here, WSL2, windows freshly install

/home/xx/.local/share/mise/installs/poetry/1.8.2/venv/bin/python3: error while loading shared libraries:

workaround

• use python compile installation, set mise flag to compile python, reinstall with --force

[Nickersoft]

Can confirm am facing this same issue 😭 @wasdee What is the full command you're running as a workaround?

Can confirm am facing this same issue 😭 @wasdee What is the full command you're running as a workaround?

suppose, I want to use 3.11.1. and i got a pre-compiled one installed. and already install pre-compile pkgs

$ mise settings set python_compile true

# maybe explicitly uninstall first
$ mise install python@3.11.1 --force

$ mise use -g python@3.11.1 

$ mise  use -g poetry@latest

This is what i vaguely remember.

same issue. i hope this can be fixed soon. as a workaround i installed pipx, then poetry using pipx

[jdx]

the precompiled pythons don't work with poetry. You need to reinstall python after running mise settings set python_compile 1. I don't know why they don't work with poetry but the issue is upstream.

[mustafa0x]

an upstream issue needs to be filed, it seems. i couldn't find one.

Note, it's not that precompiled Pythons don't work with poetry, it's that precompiled linux-musl Pythons don't work with poetry. As mentioned in https://github.com/indygreg/python-build-standalone/issues/261 there's some mystery where sometimes mise installs the linux-musl Python and sometimes installs the linux-gnu Python.

On this particular laptop it chose linux-gnu and thus I can install poetry with a prebuilt Python just fine:

% mkdir test
% cd test
% mise u python@3.10
mise installing precompiled python from indygreg/python-build-standalone
mise if you experience issues with this python (e.g.: running poetry), switch to python-build
mise by running: mise settings set python_compile 1
mise python@3.10.14 ✓ installed
mise ~/test/.mise.toml tools: python@3.10.14
mise python@3.10.14 node@20.13.1                                                                                                                               
% mise u poetry
mise plugin:poetry ✓ https://github.com/mise-plugins/mise-poetry.git#431c335                                                                                   mise poetry@1.8.3 ✓ installed
mise ~/test/.mise.toml tools: poetry@1.8.3

% which poetry

% poetry --version

Yeah, just to clarify: the musl builds have a bunch of limitations (see: https://github.com/indygreg/python-build-standalone/issues/86) -- for example, you can't load shard library-based extension modules.

It would be nice if we could avoid this specific issue in python-build-standalone (i.e., pip failing on a dlopen call), but you generally want to be using the non-musl builds. If the musl builds are being installed, there may be an issue here rather than in python-build-standalone?

[jdx]

frankly I have no idea what it does, but this change does appear to have fixed this issue for users using mise-poetry: https://github.com/mise-plugins/mise-poetry/commit/431c335b47be548500c50bd631e30a66b4370788

of course if you just pip install poetry that won't get used though

[charliermarsh]

Interesting... I submitted a PR to pip that I think would avoid this specific failure: https://github.com/pypa/pip/pull/12716. But not sure if it will be accepted or on what timeline it would be released. It should resolve the issue from the python-build-standalone side though, I think.
