Я использую ма c, и я недавно переключился с python2 на python3. После этого я не смог установить jupyter на свой ноутбук из-за некоторых проблем с зависимостями. После большого количества проб и ошибок я просто удалил Python 3 и вместо него установил brew.
Я использовал следующие руководства для удаления 1 , 2 .
Пост, что я снова установил jupyter, и теперь я сталкиваюсь с этой проблемой:
$ pip install --index-url '..' --trusted-host '..' jupyter
Так я обычно устанавливаю пакеты на свой ноутбук за брандмауэром и это работает. Но теперь я получаю следующее исключение:

Я установил прокси, и это можно увидеть с помощью env. Я также попробовал:
export http_proxy="http://<hostname>:<port>"
export https_proxy="https://<hostname>:<port>"
Кажется, ничего не работает.
Любые предложения будут полезны.
