Poetry build is ignoring the virtual environment Python when building and instead using the Python it has been installed against

OS: maOS 11.1 (Big Sur) Python: 3.8.5 (pyenv)

Poetry build is ignoring the virtual environment Python when building and instead using the Python it has been installed against.

When I install poetry with brew, it builds a Python 3.9 wheel and I get ERROR: infima-0.71.9-cp39-cp39-macosx_11_1_x86_64.whl is not a supported wheel on this platform.. When I install poetry with pipx, it builds a wheel for macosx_10_16 (which does not exist), but I am able to install it.

Steps to reproduce:

$ brew install poetry
$ poetry build
Building infima (0.71.9)
  - Building sdist
  - Built infima-0.71.9.tar.gz
  - Building wheel
running build
running build_py
package init file 'src/infima/datasets/embs/sec/sql/__init__.py' not found (or not a regular file)
running build_ext
  - Built infima-0.71.9-cp39-cp39-macosx_11_1_x86_64.whl

Then after brew uninstall poetry:

$ pipx install poetry --python python3.8
$ poetry build
Building infima (0.71.9)
  - Building sdist
  - Built infima-0.71.9.tar.gz
  - Building wheel
running build
running build_py
package init file 'src/infima/datasets/embs/sec/sql/__init__.py' not found (or not a regular file)
running build_ext
  - Built infima-0.71.9-cp38-cp38-macosx_10_16_x86_64.whl

$ poetry config --list
cache-dir = "/Users/matteosantamaria/Library/Caches/pypoetry"
experimental.new-installer = true
installer.parallel = true
repositories.gitlab.url = "https://gitlab.com/..."
virtualenvs.create = false
virtualenvs.in-project = null
virtualenvs.path = "{cache-dir}/virtualenvs"  # /Users/matteosantamaria/Library/Caches/pypoetry/virtualenvs

We ran into this on OSX. In our case we were telling poetry to not create a virtualenv but it insisted on writing to a virtualenv in the $HOME/Library/Caches/pypoetry/... dir. We fixed this by blowing away the $HOME/Library/Caches/pypoetry directory.

Using this workaround, it still works for us when we are using python 3.8 in our application and poetry is depending on python 3.10 as it does when installed from brew.

hth.

(search terms: work around, fix).

@sinoroc https://gist.github.com/iserko/1e88e05675e360b23d52bac65c3baced replicated on Debian Buster (where poetry is installed using Homebrew and uses the Homebrew’d Python 3.9)
