[BUG] Install fails with use_2to3 is invalid error #3898

@mattclay

Description

@mattclay

setuptools version

67.7.0

Python version

3.8

OS

Ubuntu 22.04.2 LTS

Additional environment information

Use of pip 23.1 is required for the reproducer given, since it relies on --no-binary attempting to build a wheel.
Additionally, wheel should not be installed for the reproducer to work.

The changes in #3849 seem related.

Description

Installation of coverage version 4.5.4 fails with setuptools version 67.7.0, but works with 67.6.1.

As a work-around, I can use the previous version of setuptools:
