Pip: IOError: [Errno 13] Berechtigung verweigert: '/usr/local/bin/pip'

• Pip -Version: 1.5.4
• Python -Version: 2.7.6
• Betriebssystem : Ubuntu 14.04

Beschreibung:

Wie kann ich folgendes Problem lösen:

Ich habe versucht, autograd und scikit-learn zu installieren, beide über den Befehl pip. Beide Installationen sind jedoch mit dem Fehler fehlgeschlagen
OSError: [Errno 13] Permission denied: '/usr/local/lib/python2.7/dist-packages/pip'

Daher denke ich, dass dieser Fehler durch Pip verursacht werden kann, also teste ich Pip mit dem Update-Befehl 'pip install -U pip ', er antwortete
IOError: [Errno 13] Permission denied: '/usr/local/bin/pip'

Ich vermute, Pip auf meiner Maschine ist kaputt? Jeder Rat ist ziemlich zu schätzen, danke.

Was ich gelaufen bin:

Das Protokoll des ausgeführten Befehls „pip install -U pip“ ist unten aufgeführt:
