Incorrect installation of extras packages for multiple conditions

• I am on the latest Poetry version.

• I have searched the issues of this repo and believe that this is not a duplicate.

• OS version and name: macOS 10.15

• Poetry version: 1.1.4

Issue

[tool.poetry.dependencies]
python = "^3.8"
requests = [
    { version = "==2.24.0", python = "~3.8", optional = true },
    { version = "==2.25.0", python = "~3.9", optional = true }
]

[tool.poetry.extras]
req = ["requests"]

[tool.poetry.dev-dependencies]

[build-system]
requires = ["poetry-core>=1.0.0"]
build-backend = "poetry.core.masonry.api"

When I install my package geneated by poetry build with the above pyproject.toml file, I don’t think it behaves correctly under some conditions.

Specifically, when I run pip install my_package-0.1.0-py3-none-any.whl,

• in python 3.9
  • expected: not install
  • actual: requests==2.25.0 is installed. <- Incorrect!
• in python 3.8
  • expected: not install
  • actual: not install

I think there is a problem with the files generated by poetry build, as it works correctly with poetry install.

metadata today says:

Requires-Dist: requests (==2.24.0); (python_version >= "3.8" and python_version < "3.9") and (extra == "req")
Requires-Dist: requests (==2.25.0); (python_version >= "3.9" and python_version < "3.10") and (extra == "req")

which is correct, this can be closed

Same thing happening for me. Does nobody have a workaround or know if this works in an older version?
