Manifest generation for projects only using Python in pre-rendering should include Python

I have a project in which I only use a Python script in pre-rendering, but not in any .qmd files. Generating a manifest through:

rsconnect write-manifest quarto . --overwrite

causes the "python" section to not appear, which prevents the requirements.txt from being included, and it seems no Python environment is set up when deploying. The pre-render scripts then fail because they can't import my dependencies.

As a workaround I just added an empty Python cell to one of my .qmd files.

It would be nice if the manifest would also include Python things when there are Python scripts used in pre-rendering.

Inizia riproducendo rsconnect write-manifest quarto . --overwrite con un progetto che utilizza Python solo in uno script di pre-rendering, quindi esamina il percorso di generazione del manifest di Quarto. Confronta il risultato con un progetto contenente una cella Python; il lavoro è completato quando il manifest include la sezione Python e requirements.txt, così che il deployment configuri l'ambiente per lo script di pre-rendering.
