Depencendy listed in `poetry.lock` is not installed

• I am on the latest Poetry version.
• I have searched the issues of this repo and believe that this is not a duplicate.

Issue

Hi!

I currently have a project structure similar to:

├── first_package
│   ├── first_package
│   │   └── __init__.py
│   └── pyproject.toml
├── second_package
│   ├── pyproject.toml
│   └── second_package
│       └── __init__.py
└── third_package
    ├── poetry.lock
    ├── pyproject.toml
    └── third_package
        └── __init__.py

Where third_package depends on second_package which in turn depends on first_package and first package depends on psycopg2-binary = "2.8.5". The dependencies third_package -> second_package as well as second_package -> first_package are created using a path dependency, where develop is set to true. E.g.:

second_package = { path = "../second_package", develop = true }

I set develop to true as this seems to mitigate https://github.com/python-poetry/poetry/issues/3368 (in the real usecase, these projects might have different root directories).

When I now poetry lock in the third package, it looks as expected:

However, after a poetry install, psycopg2 is missing in the environment. This issue does not occur on one level of nesting (e.g. psycopg2 being a dependency of second_package)

I added a zip of my minimum example if you would like to try this yourself: poetry_dependency_bug.zip

Hi, I encountered the same issue. Just FYI personally I don’t have this issue with 1.1.4 and 1.1.5, it starts with 1.1.6.

The root cause has been identified (see #4202) and this will be fixed in the next bugfix release.

Note that you will to regenerate the lock file for the fix to take effect.
