Почему Seaborn не устанавливается на PyCharm или в командной строке?

Когда я пытаюсь установить Seaborn в PyCharm, добавив пакет в мои доступные пакеты, я получаю сообщение об ошибке

Ненулевой код выхода (1)

Это обеспечивает предлагаемое решение, которое состоит в следующем:

Попробуйте запустить эту команду ( pip install seaborn) из системного терминала. Убедитесь, что вы используете правильную версию pip, установленную для вашего интерпретатора Python, расположенную в /usr/bin/python2.7.

Когда я запускаю команду в терминале, я получаю следующую ошибку:

Сбой команды "python setup.py egg_info" с кодом ошибки 1 в / tmp / pip-build-edImGe / matplotlib

Полный терминал выглядит так:

В верхней части этого журнала написано следующее:

Вы используете версию 7.1.0 pip, однако доступна версия 9.0.1. Вы должны рассмотреть возможность обновления с помощью команды 'pip install --upgrade pip'.

Поэтому я попытался обновить pip с помощью следующей команды: pip install --upgrade pipкоторая вызвала больше ошибок, а именно:

что я делаю не так и что я должен сделать, чтобы установить Seaborn?
