Как установить PyObjC на Python 3.5 (OS X 10.10 Yosemite)?

Question

Я пытаюсь установить PyObjC с помощью pip3 install pyobjc-core, на Mac с Python 3.5 и OS X 10.10.5 (Yosemite). Я получаю следующее сообщение об ошибке:

Подобного, если я пытаюсь просто сделать pip3 install pyobjc, я получаю подобный трекбек, заканчивая эти фатальные словами:

Command "python setup.py egg_info" failed with error code 1 in /private/var/folders/v0/bzvt8grs6mv33_j13_wdwqs80000gr/T/pip-build-432fq8a3/pyobjc-core/ 

надежда на меня, или там, например, какая-то известная несовместимость с системной версией Python?

Я месяц поздно здесь, но первая строка ошибки:

xcode-select: error: tool 'xcodebuild' requires Xcode, but active developer directory '/Library/Developer/CommandLineTools' is a command line tools instance

Вам необходимо установить полную версию Xcode из магазина приложений не только инструменты командной строки. :)
