Reinstall pipx apps after Homebrew Python upgrade
I install Python apps on my Mac using pipx like this:
pipx install rst2pdf
This will then install rst2pdf into its own isolated environment so that its dependencies do not affect and are not affected by any other Python app I have installed.
Internally, it creates a venv at /.local/pipx/venvs/rst2pdf with symlinks to the currently installed python in the bin directory:
lrwxrwxr-x@ 1 rob staff 10 24 May 2023 python -> python3.11 lrwxrwxr-x@ 1 rob staff 10 24 May 2023 python3 -> python3.11 lrwxrwxr-x@ 1 rob staff 96 24 May 2023 python3.11 -> /opt/homebrew/Cellar/[email protected]/3.11.3/Frameworks/Python.framework/Versions/3.11/bin/python3.11
All is good.
However, when the Homebrew version of Python is updated, the old version is removed.
Running rst2pdf now fails with “cannot execute: required file not found” as the linked python no longer exists.
It’s easy enough to fix when you work out what’s happened:
pipx reinstall-all
I wish this situation was handled a little bit better though.
