Issue

I have two local packages, pack-1 and pack-2. When I add the pack-1 to the pack-2 (poetry add --editable ../pack-1) the pack-1 is added to the pyproject.toml of the pack-2, but when I import the module pack_1 (in any of the pack-2 files) I have the error No module named 'pack_1'.

pack-1 pyproject.toml:

[tool.poetry]
name = "pack-1"
version = "0.1.0"
description = ""
authors = [""]
readme = "README.md"
packages = [{include = "pack_1"}]

[tool.poetry.dependencies]
python = "^3.11"

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

pack-2 pyproject.toml:

[tool.poetry]
name = "pack-2"
version = "0.1.0"
description = ""
authors = [""]
readme = "README.md"
packages = [{include = "pack_2"}]

[tool.poetry.dependencies]
python = "^3.11"
pack-1 = {path = "../pack-1", develop = true}

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

In MacOS the expected behavior (the module being available to pack-2) is successful. I've been only experiencing this on Windows 11.

Let me know if you need any more info.
