Error message during pip install

[Riduidel]

During pip install, I had the following error message

Collecting colorama
  Using cached colorama-0.4.6-py2.py3-none-any.whl (25 kB)
Installing collected packages: sgmllib3k, MarkupSafe, itsdangerous, feedparser, colorama, Werkzeug, Jinja2, click, Flask
  DEPRECATION: sgmllib3k is being installed using the legacy 'setup.py install' method, because it does not have a 'pyproject.toml' and the 'wheel' package is not installed. pip 23.1 will enforce this behaviour change. A possible replacement is to enable the '--use-pep517' option. Discussion can be found at https://github.com/pypa/pip/issues/8559

  note: This error originates from a subprocess, and is likely not a problem with pip.

It seems sgmllib was dropped in Python 3. For those depending on it, that’s somewhat unfortunate. Have you tried to use the project without it ?

Ultimately,I think requirement.txt file could be simplified with just: feedparser==6.0.10 Flask==2.2.3 Werkzeug==2.2.3

[Riduidel]

Install command line (to document in readme) should be pip install -r requirements.txt --use-pep517 --user

The --use-pep517 is required by sgmllib (a dependency of feedparser) and the --user is required by flask
