Trying to solve a pip-compile stack trace error

Question

When I run pip-compile I get an error telling me that

AttributeError: 'InstallRequirement' object has no attribute 'use_pep517'

I am using

• Python 3.11.6
• pip v25.3
• pip-compile v7.5.1

From other threads, I suspect that there is a compatibility issue between pip and pip-compile versions, but I couldn't find any information on the compatibility mix.

I have tried a number of things to resolve this

• Clearing down my pyenv virtualenvs and rebuilding
• Upgrading to Python 3.11.14
• Upgrading to Python 3.13.8
• Reducing the requirements.in file down to one library rather than everything the app needs. I have tried each library in turn as an individual.

Nothing I have done has had any effect. I can't think what else I can do to resolve this and should be grateful for any help.

Answer 1

The recommendation supplied by Dunes solved the issue. It seems that pip 25.3 is causing the compatibility issue.

Run:

pip install -U 'pip<25.3'

And pip-compile runs smoothly again.
