Poetry does ignores extras_require packages defined in setup.py

[NixBiks]

• I am on the latest Poetry version.
• I have searched the issues of this repo and believe that this is not a duplicate.
• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

• OS version and name: both debian and macOS
• Poetry version: 1.1.2

Issue

If I run the following poetry add 'camelot-py[cv]' then I correctly get the following in pyproject.toml

[tool.poetry.dependencies]
python = "^3.8"
camelot-py = {extras = ["cv"], version = "^0.8.2"}

But opencv-python is not installed as stated in extras_require in setup.py. If I use pip install 'camelot-py[cv]' then it works as expected

I've confirmed this bug with poetry add modin[dask]

It doesn't happen with poetry=1.0.10

Can you please try the fix at #3147.

Using pipx

pipx install --suffix=@3147 'poetry @ git+https://github.com/python-poetry/poetry.git@refs/pull/3147/head'

Using a container (podman | docker)

podman run --rm -i --entrypoint bash python:3.8 <<EOF
set -e
python -m pip install -q git+https://github.com/python-poetry/poetry.git@refs/pull/3147/head
python -m poetry new foobar
pushd foobar
sed -i /pytest/d pyproject.toml
python -m poetry add 'camelot-py[cv]'
EOF
