[email protected] installed using python3.11 is unable to install dependencies using file: urls.

[lucamuscat]

Description

Hey 👋

When using a version of [email protected] installed using python3.11, projects depending on local projects
by declaring dependencies using the file url (whilst also using the PEP508 specification) fails to
install said project with the following error: The requirement is invalid: invalid URL "file:../dummy".

Note that this error does not occur when poetry is installed using python3.12.

Reproduction

I've created a repository containing a dockerfile which reproduces this bug, and validates that this error does not occur when installing poetry using python3.12, which you may find here.

Workarounds

Install poetry using python3.12

https://python-poetry.org/docs/dependency-specification/#path-dependencies

In the project section, you can only use absolute paths

Use the rich syntax instead https://python-poetry.org/docs/dependency-specification/#path-poetry.

[dimbleby]

this is not a path dependency (though perhaps it should have been)

looks like there has been a change in behaviour of urllib.parse.urlunparse() in python 3.13.

from urllib.parse import urlparse, urlunparse
parsed = urlparse("file:../dummy")
unparsed = urlunparse(parsed)
print(unparsed)

gives either file:../dummy or file:///../dummy depending on version

You'd probably need to go spelunking through cpython commits - or ask over there - to figure out whether this is intended or correct
