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.

まず、Python をプレレンダースクリプトでのみ使用するプロジェクトで rsconnect write-manifest quarto . --overwrite を再現し、その後 Quarto のマニフェスト生成パスを調べます。Python セルを含むプロジェクトと結果を比較します；完了の条件は、マニフェストに Python セクションと requirements.txt が含まれ、デプロイ時にプレレンダースクリプト用の環境がセットアップされることです。
