I was using Big Sur with Python 3.8.2 (not Homebrew's, but native OS' Python) and I had a lot of packages installed (around 60). Now I updated my OS to Monterey 12.6 and I updated Xcode to 14.0 which updated Python to 3.9.6. And I had a very nasty surprise - all of my packages are gone. There is not a single package I installed when I was using Python 3.8.2. I sure hope it didn't delete them for good. I found some of them in ~/Library/Python/3.8 but not all. If I knew this would happen, I would use pip freeze. How can I fix this?
