Раньше я мог запускать команду pip из блокнота jupyter. Но теперь, даже если я возьму с собой даже базовые ! pip -V, я получу:

Возможно, причина в том, что я попытался установить Python из Microsoft Store, в котором не было pip, и что я скачал pip ниже этот урок
Я пытался установить его из sys:
import sys
!{sys.executable} -m pip install facebook_sdk]
Но получил следующее:

Я пытался установить его (и случайный пакет) с conda install pip, но получил почти такую же ошибку

Но все равно возникла ошибка после выключения ядра и закрытия оконного терминала jupyter.
