I ran into this same issue trying to install different packages in a few unrelated projects last week. `python -m pip install --upgrade pip` fixed the issue each time. All of them were failing with pip 19.x and working with, IIRC, v24.x Best, David Lakin -- On Mon, Apr 1, 2024, at 14:56, Stefan Behnel wrote:

I'm attempting to develop a project that has been operational for a while. The project makes use of mixbox which references this library. It seems that version 5.2.0 of lxml was released yesterday. Strangely, pytoml is encountering an error related to the pyproject.toml file. Can someone investigate this issue?

Could you state the platform/architecture that you're running? And which Python version? I wonder why it picks up the source distribution instead of a ready-made binary wheel. lxml takes a while to build and requires external system libraries, so building from source is discouraged for "normal" use.

This seems to use an old version of pytoml, a library which (apparently) has been deprecated in favour of other tools.

I'd try upgrading your build environment (pip, setuptools, wheel, etc.).
