Skipping C:\path\to\vtk-9.2.6.egg-info due to invalid metadata entry 'name'

Issue

While using a conda-forge environment with vtk installed, I also do local development on other packages. For instance mypackage with pyproject.toml:

[build-system]
requires = ["setuptools"]
build-backend = "setuptools.build_meta"

[project]
name = "mypackage"
version = "0.0.1"
dependencies = ["vtk"]

to work with this package:

cd mypackage
pip install --dry-run -e .

which creates the output:

and yes, I did cancel the operation to download vtk from pypi, since it is already installed to the test environment from conda.

Looking at the Core metadata specifications docs, the required entries are:

• Metadata-Version
• Name
• Version

However, the .egg-info file is missing "Name".

One possible resolution is to amend the .egg-info file as:

Metadata-Version: 2.1
Name: vtk
Version: 9.2.6
Summary: VTK is an open-source toolkit for 3D computer graphics, image processing, and visualization
Platform: UNKNOWN

which has better output from pip install --dry-run -e .:

Obtaining file:///D:/src/mypackage

Requirement already satisfied: vtk in c:\users\mtoews\appdata\local\miniforge3\envs\test\lib\site-packages (from mypackage==0.0.1) (9.2.6)
Would install mypackage-0.0.1
