Priority of .egg-info, .dist-info, and setup.py

Issue

This is arguably not a poetry issue, but I think it'd be nice if poetry or its dependencies did something to avoid the problem I'm having. In addition to the pyproject.toml file I linked above, my toy example here also contains the directory foo whose only contents is this setup.py file.

To reproduce the problem I'm having, do the following:

1. Run pip install -e foo.
2. Modify the setup.py file to depend on another package such as requests.
3. Run poetry lock.

The problem here is that step (1) creates a foo.egg-info directory which poetry lock uses in step (3) despite the setup.py file being modified to include other dependencies in step (2). Using the packages from my example here, poetry.lock only includes urllib3 and not requests which I added as a dependency in step (2).

Can poetry or its dependencies do something to avoid this issue?

Start with the linked pyproject.toml and foo/setup.py, then reproduce the sequence of pip install -e foo, modifying setup.py, and poetry lock. Trace how the generated foo.egg-info is used during locking; done means the lock reflects the updated requests dependency instead of stale metadata.
