extra incorrectly shown on installation error

[notatallshaw]

Description

When you install a requirement with an extra and are no distributions for that extra you get a slightly misleading message from the installation error.

Expected behavior

Remove the extra from the requirement.

pip version

25.2

Python version

3.14

OS

Linux

How to Reproduce

pip install --dry-run fsrs[optimizer]==6.2.0

Output

Collecting fsrs==6.2.0 (from fsrs[optimizer]==6.2.0)
  Using cached fsrs-6.2.0-py3-none-any.whl.metadata (13 kB)
INFO: pip is looking at multiple versions of fsrs[optimizer] to determine which version is compatible with other requirements. This could take a while.
ERROR: Could not find a version that satisfies the requirement torch; extra == "optimizer" (from fsrs[optimizer]) (from versions: none)
ERROR: No matching distribution found for torch; extra == "optimizer"

This line is confusing:

ERROR: No matching distribution found for torch; extra == "optimizer"

It comes directly from the distribution metadata and is used to refer to the fact that torch is an extra of fsrs, but taken out of that context it looks like pip is looking for torch with the extra optimizer. The message should read:

ERROR: No matching distribution found for torch

Code of Conduct

• I agree to follow the PSF Code of Conduct.

Just noting for future readers that at the time of writing, torch is not currently supported in python 3.14 which is why this specific error exists.

Yes, if / when #13520 lands I'll update the steps to reproduce to continue to work in the future.
