What are the new commands & or equivalents of:
python_select -L (shows available python versions)
python_select -s (sets the default version of your choice of python).
I know they have changed to --list, --set, --show but there doesn't seem to be an example of how to properly use each one. For example, if I use port select --set I get the following:
Error: port select [--list |--set |--show] [].
To list:
port select --list python
To show:
port select --show python
To select:
sudo port select --set python <the python version>
