Запуск команды pip через прокси не работает

Question

Адрес прокси внутри организации выглядит следующим образом: http://proxy-europe.network.CorporateName.com/. Как гуглил и исследовал на stackovetrflow, способ обойти прокси при работе pip должен использовать

pip install --proxy=https://proxy-europe.network.CorporateName.com pandas

но это не работает для меня:

C:\Users\3626416>pip install --proxy=http://proxy-europe.network.CorporateName.com pandas

Любой совет относительно того, что я делаю неправильно? Большое спасибо.
