ичок в Python и хочу установить пакет Pillow на Mac для Python 3.5. Я используюpip install pillowкоманда и получите эту ошибку:

Jaspers-MBP:~ jasperherrmann$ pip install pillow

Поэтому я продолжаю и пытаюсь установить все вещи, которые pandas, html5lib и т. Д. Требуютpip install six, pip install numpy а такжеpip install python-dateutil и получите следующую ошибку (для всех команд одинаковая):

Jaspers-MBP:~ jasperherrmann$ pip install six
Requirement already satisfied: six in /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python (1.4.1)
prompt-toolkit 1.0.15 has requirement six>=1.9.0, but you'll have six 1.4.1 which is incompatible.

jupyter-client 5.2.3 has requirement python-dateutil>=2.1, but you'll have python-dateutil 1.5 which is incompatible.

Так что я подумал, что все в порядке шесть, а остальные уже есть, и мне просто нужно обновить их сpip install --upgrade six команда. И вот, где я получил последнюю ошибку, а теперь нет, как продолжить:

Jaspers-MBP:~ jasperherrmann$ pip install --upgrade six

Cannot uninstall 'six'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.
Jaspers-MBP:~ jasperherrmann$ 

Так что вот я застрял и был бы рад, если у кого-то из вас есть решение моей проблемы :-)
