README

        
This repo demonstrates the problem of "offline installations of a package with a VCS URL dependency fails even if the dependency is already installed."

This was tested with `pip 22.1.2`, but as far as I know can be reproduced on any version of `pip` since the new resolver was rolled out.

1. With a connection to the internet, `pip install .` pulls the VCS URL at install time and succeeds:

2. If you then disconnect from the internet and try to `pip install .` again, the package will fail to install with an error like:

```

pip install .

3. If you instead opt for the legacy resolver via `pip install . --use-deprecated legacy-resolver` it will succeed (assuming the dependency has been installed previously):
