pip installs numpy but poetry does not

• I am on the latest Poetry version.

• I have searched the issues of this repo and believe that this is not a duplicate - I think it’s here (https://github.com/python-poetry/poetry/issues/1516, or here https://github.com/python-poetry/poetry/issues/3153 - but i’ve done the work arounds ([“setuptools”, “poetry_core>=1.0”]) and nothing)

• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

• OS version and name: Latest Big Sur - 11.2.3

• Poetry version: Poetry version 1.1.4

Issue

Hi – I’ve seen a bunch of other issues related to numpy, and know it’s a numpy problem on Big Sur EXCEPT i think i’ve done everything right (in re upgrading), and I still get the following - works when I install numpy directly via pip, but fails from poetry. What should I do here?
