You actually can but it's not documented I guess. I remember finding it when I dug the source code.

[tool.poetry.dependencies] my-package = { "path" = "path/to/package", develop = true }

This way you can patch my-package and poetry will always install the latest state of it.

But I can’t do it from pip to another poetry package. I have to be using poetry for it.

Ah got it, I see what you mean now. In cases like this I had to build the wheel and install it which is not great indeed.
