Poetry doesn't appear to allow for efficient docker caching when using /src

Feature Request

From: https://python-poetry.org/docs/pyproject/#packages%C2%A0

If your package is included in a subdirectory (i.e. /src), you need to include the path as follows:

[tool.poetry]
# ...
packages = [
    { include = "my_package", from = "src" },
]

The problem is that if you have an actively developed package it's generally more efficient to cache requirements in the base image. This is normally easily accomplished by running poetry install --no-dev --no-interaction

Unfortunately, if you have a /src directory and implement the package syntax, poetry will fail if the package is not there with the following error

/src/my_package does not contain any element

Suggestion/feature request: a flag to skip the packages block when installing the base image

Hello @curtiscook,

I don't really understand your use-case. But is the --no-root parameter for poetry install what you are looking for?

it's not clear that --no-root supports skipping packages?

If it does, it could possibly work?

As for my use case --

I want to install the base image with deps into an intermediate container & then install my package into a new container. This increases docker's ability to cache the repo. Currently, it wants to just fail the build. Maybe this should throw a warning w/ a suggestion with --no-root?

I was able to work around it, but everything feels very abusive/hacky so I think that there should be more direct support (or documentation) for docker builds

I'm not familiar with the docker stuff. But that sounds exactly like what --no-root is doing. It installs all you dependencies, but will not install the project's package itself.
