py37-ipython has the following notes:
Please note that since version 4.0 IPython was refactored and splitted across several packages under new project named Jupyter.
To make this the default IPython or IPython3 (i.e., the version run by the 'ipython' or 'ipython3' commands), run one or both of:
sudo port select --set ipython py37-ipython
sudo port select --set ipython3 py37-ipython
py37-pygments has the following notes:
To make the Python 3.7 version of Pygments the one that is run when you execute the commands without a version suffix, e.g.
'pygmentize', run:
port select --set pygments py37-pygments
とこんなコメントが出てくる。（python3.7の場合）
