#69306: Jupyter notebooks fail to launch

 Keywords:  jupyter    |       Port:  py-jupyter
-----------------------+------------------------
 The MacPorts versions of the Jupyter notebook stack crash on launch with
 this issue: https://github.com/jupyter/notebook/issues/7048

 {{{
 ModuleNotFoundError: No module named 'jupyter_server.contents'
 }}}

 I can confirm that uninstalling MacPorts {{{py*-traitlets}}} and using
 {{{pip3 install traitlets==5.9.0}}} is a temporary fix.

 But MacPorts versions of Jupyter ports are many versions out of date and
 must be updated to address this issue.
