Poetry fails if a local dep is missing while only defined as extra

Issue

Poetry does not manage to handle missing deps defined as extra, even though a complete poetry.lock exists and has been generated previously.

Workflow to generate the error:

• create an dummy project in tmp-0
• create tmp-1 project. Add tmp-0 as extra deps as above.
• poetry env remove python && rm -rf ../tmp-0 to start over fresh
• poetry install fails

> poetry install
  ValueError

  Directory ../tmp-0 does not exist

The use case is: I am working on two packages simultaneously with the second one depending on the first one. When I am developing, I want to have the tmp-0 I am working on installed in develop mode, but elsewhere a true dep declared as any other

Hi !

I am running in the same issue with optionable path to wheels (like prodi.gy ones) without develop mode.
I think all commands requiring the pyproject.toml fail :

• poetry install even without the extra
• poetry config

Expected results

Everything works without checking the path.
poetry install -E poetry fails if the user does not have the required files.
I am not clear on the process for poetry update, but I think it may be normal to require the paths locally.

Error log

  ValueError
  Directory does not exists
  at ~/.poetry/lib/poetry/_vendor/py3.8/poetry/core/packages/directory_dependency.py:41 in __init__
       37│         self._develop = develop
       38│         self._supports_poetry = False
       39│
       40│         if not self._full_path.exists():
    →  41│             raise ValueError("Directory {} does not exist".format(self._path))
       42│
       43│         if self._full_path.is_file():
       44│             raise ValueError("{} is a file, expected a directory".format(self._path))

Note : it's probably related to the poetry.lock has it fails after changing the pyproject.toml

Hi,

Bumping this as gently as possible :)

I am still blocked by this : I have the lines commented in my pyproject.toml and have to explicitely ask people to uncomment, update, and run the install in the docs.

Is this something I could help poetry on or would the fix be too complex ?

[Wirg]

Hi !

Any updates on this ? :)
