I couldn't install numpy using poetry on macOS Big Sur, so I forcibly avoided it

environment

Event that occurred

When I did poetry install with the following description in pyproject.toml

[tool.poetry.dependencies]
python = "3.8.*"
pip = "^20.3.3"
gcsfs = "^0.7.1"
lightgbm = "^3.1.1"
pandas = "^1.2.0"
matplotlib = "^3.3.3"
seaborn = "^0.11.1"
% poetry install

Python 2.7 will no longer be supported in the next feature release of Poetry (1.2).
You should consider updating your Python version to a supported one.

Note that you will still be able to manage Python 2.7 projects by using the env command.
See https://python-poetry.org/docs/managing-environments/ for more information.

Workaround

It can be installed using pip 20.3.3 without using poetry (using python 3.9, but also with python 3.8)

% python3.9 -m venv --upgrade-deps venv

So, if you use pip, you can solve it. ** But not recommended **. If you try to output requirements.txt with poetry, it's okay ...

% poetry config virtualenvs.create false
% python3.8 -m venv .venv && source .venv/bin/activate && pip install -U pip && (poetry export --without-hashes > requirements.txt) && pip install -r requirements.txt && deactivate

After that, if you do poetry install, it will pass, and poetry shell will also pass, but the feeling of korejanai is amazing. I want to solve it better.
