Tidying up Python

[Steven Smith]

You want the command port installed, not port list, to see everything that you’ve installed before.

If you really do have this cold versions installed, it’s also likely that you also have zillions of old Python version packages installed too:

> port installed py*


Here’s a gist I use to migrate to new versions of Python:

https://gist.github.com/essandess/29067dc7b50536aa0a1f9f34fece73a7

To get an up-to-date Python install, choose the latest version whose packages both exist and work, likely python313:

> $ port list py3*-jupyter
> py39-jupyter                   @1.0.0          python/py-jupyter
> py310-jupyter                  @1.0.0          python/py-jupyter
> py311-jupyter                  @1.0.0          python/py-jupyter
> py312-jupyter                  @1.0.0          python/py-jupyter
> py313-jupyter                  @1.0.0          python/py-jupyter


Then:

> sudo port -pNc install py313-jupyter

> port select --set jupyter py313-jupyter
