Can not install package in CI

[PythonFZ]

Description

All my poetry projects CI fails with the latest release.
They are using

   steps:
      - uses: actions/checkout@v4
      - name: Set up Python ${{ matrix.python-version }}
        uses: actions/setup-python@v5
        with:
          python-version: ${{ matrix.python-version }}
      - name: Install Poetry
        uses: snok/install-poetry@v1
        with:
          virtualenvs-create: true
          virtualenvs-in-project: true
      - name: Install package
        run: |
          poetry install --no-interaction

and just fail with

Installing the current project: znsocket (0.2.8)

'Repository'
Error: Process completed with exit code 1.

This seems more or less independent of the requirements as different packages are affected, e.g.:

• https://github.com/zincware/ZnSocket
• https://github.com/zincware/ZnDraw
• https://github.com/zincware/rdkit2ase
• https://github.com/zincware/ZnTrack
• ...

Same for me. I had to add a packages section in tools.poetry in pyproject.toml for one build to work. But another project which uses submodules is failing to import modules within the submodules even with that fix

[boltzmann-brain]

my project structure is:

+--project_name
| +-- pyproject.toml
| +-- src (where all the modules to be installed are)

Previously in pyproject.toml I did not have a packages section in [tool.poetry]. This was fine until 2.0.0. With 2.0.0, I get
Warning: The current project could not be installed: No file/folder found for package [project_name]

I made the change adding the following to [tool.poetry] in pyproject.toml:

packages = [
    { include = "src", from = "." }
]

This worked for one project, but for another project, although it also helped avoid the error above, I got a different error about not finding modules in a submodule.
