Unable to install libxml2-python3 #12027

Closed MarkR42 closed 1 year ago

MarkR42 commented 1 year ago

Description

Latest version of pip fails to install libxml2-python3

Python 3.8 Linux 64-bit.

An older version of pip, 23.0.1, can successfully install this package.

I am using a virtualenv.

Expected behavior

Successfully installed libxml2-python

pip version

23.1.2

Python version

3.8.13

OS

Oracle Linux 8.5 64-bit

How to Reproduce

  1. Create virtualenv
  2. Activate virtualenv
  3. pip install --verbose libxml2-python3

Output

ERROR: Could not install packages due to an OSError.

This seems to be an issue with the libxml2-python3 package and should be reported to the project maintainers instead.

pip has recently transitioned from using PEP 517 to build packages when setuptools and wheel are not present for legacy setups, which is why you see the behaviour change.

To work around the issue: pip install setuptools wheel
