Failed parsing requirement error for local dependency

Release https://github.com/pypa/pipenv/releases/tag/v2022.8.24 introduces a bug about resolving local dependencies with a relative path.

Our setup has a local dependency described as {path = "./shared", extras = ["models", "auth0"]} in Pipfile.

pipenv install throws error: pipenv.vendor.requirementslib.exceptions.RequirementError: Failed parsing requirement from './shared#egg='

reverting to the previous release https://github.com/pypa/pipenv/releases/tag/v2022.8.19 fixes the issue for us.

I have already fixed the version to 2022.8.30 in all dockerfiles where we install pipenv. By the looks, #5320 seems to fix it. But it will be much easier for me to validate by the next release.

@mstdokumaci I see what you mean about this example, it may be a new requirementslib issue–however, if you add editable = "true", to your local dependency it appears to work. Here was the stack trace I got without having editable = "true",

$ pipenv lock
