У меня Python 3 работает на сервере Linux.Мне нужно установить некоторые библиотеки (очевидно), поэтому я пытаюсь:
pip3 install numpy
Что приводит к следующей ошибке:
Collecting numpy

ОБНОВЛЕНИЕ: Я попытался ping google.com и получил ошибку:
ping: google.com: Name or service not known
Но когда я попытался ping 8.8.8.8, я получил:
