MarsSeed [1] filed a deletion request for jupyter_nbextensions_configurator [2]:
This package is useless on its own. It was only able to work with AUR/jupyter_contrib_nbextensions, which is no longer maintained and has not received the major API compatibility overhaul that would have been necessary to make it compatible with the current jupyter-notebook 7.x that is in Arch extra repo. See deletion request PRQ#67078 for that AUR package. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/jupyter_nbextensions_configurator/
