Errors with referential optional-dependencies on 7.5.0 #2233
Description
I'm getting ValueError: relative path can't be expressed as a file URI for one optional dependency referencing another after updating pip-tools from 7.4.0 to 7.5.0.
Environment Versions
- OS Type: Ubuntu 22.04
- Python version: 3.13.2
- pip version: 25.2
- pip-tools version: 7.5.0
Steps to replicate
My pyproject.toml looks somewhat like this:
[project]
name = "da"
# ...
dependencies = [
# ...
]
[project.optional-dependencies]
utils = [
# ...
]
test = [
"da[utils]",
# ...
]Expected result
Compiled requirements.
I haven't altered my pyproject in any way after or before updating pip-tools.
Compile works after I comment out da[utils].
Actual result
$ pip-compile -o requirements.txt pyproject.toml
Using pip-tools configuration defaults found in 'pyproject.toml'.
