Почему возникает ошибка ProxySchemeUnknown при установке JayDeBeApi с помощью pip?

Question

При установке пакета JayDeBeApi возникает ошибка. Пробовал редактировать файл Conf. Пытался удалить и переустановить Python, он снова и снова выдает одну и ту же ошибку. Может кто-нибудь помочь?

$ pip3 install --proxy=https://[ID]:[PWD]@ProxyURL:Proxyport JayDeBeApi
