python@3.8 also satisfy autojump from it's homgpage

Answer 1

Impossible, that's not how Homebrew works.

Installing autojump with homebrew is basically

1. Creating a virtual environment with Python@3.9 (Homebrew always chooses the latest Python)
2. Install autojump package in that environment.

Unless you modify the autojump homebrew formula, You can't reuse python@3.8.

Answer 2

You can try the following

brew install autojump --ignore-dependencies
