Fehler beim pip installieren pyobjc

Question

Ich versuche pyobjc-core zu installieren, die eine Voraussetzung für pyautogui ist. Ich bekomme den folgenden Fehler während der Installation. Ich habe bereits setuptools aktualisiert mit pip3 install --upgrade setsetools und auch mit sudo python3 ez_setup.py. Ich bin auf OSX Yosemite und mit Python 3.5.

Ich sehe, dass der Code unten eine Anforderung für xcode hat. Könnte das der Grund sein und warum würde xcode für diese Installation benötigt?

Answer 1

yep, ist der Fehler klar, Sie Xcode müssen ... es ist albern, aber leider gibt es diese „Entwicklertools“, die an sie gebunden sind, und da viele Pakete benötigen Entwickler-Tools (in Ihrem speziellen Fall " xcodebuild "braucht es) Sie müssen xcode installieren (es ist sowieso kostenlos)
