Fehler bei der Installation von pip für Python

Question

Um Python-Pakete zu installieren, müssen Sie pip installiert haben. Sehr klare Anweisungen sind hier zu finden: https://packaging.python.org/installing/

Wenn jedoch Pip über python get-pip.py zu installieren versucht, ich die folgende Fehlermeldung:

OSError: [Errno 13] Permission denied: '/Library/Python/2.7/site-packages/pip'

Ohne Erfolg, ich habe versucht, den Rat auf GitHub folgen (https://github.com/pypa/pip/issues/3761), um meine Berechtigungen zu ändern und den Systemintegritätsschutz zu deaktivieren, den Sie unter diesem Link finden (http://osxdaily.com/2015/10/05/disable-rootless-system-integrity-protection-mac-os-x/).

Beachten Sie auch, dass pip nicht auf meinem Rechner nicht vorhanden ist:

Myname-MBP:python myname$ pip 
-bash: pip: command not found 

ich OSX 10.12.2 renne.

Lösung:

Nach Tristans versucht & Coolq B Vorschlag sudo python get-pip.py es funktionierte. Allerdings, wenn Sie nicht erfolgreich sind, versuchen Sie es erneut: Nach dem ersten Versuch habe ich einen Timeout-Fehler festgestellt. Ich habe es erneut versucht und es hat funktioniert. Beide Ergebnisse veröffentlicht:

Erster Versuch (Timeout-Fehler):
