You are using pip version 8.1.2, however version 9.0.1 is available. 
You should consider upgrading via the 'pip install --upgrade pip' command. 

Vielleicht mit ‚chown‘ gehe ich soll, aber nicht wissen, wie um es zu benutzen. Bitte helfen Sie.

Da Sie Ihre systemweite Python aktualisieren möchten, müssen Sie diesen Befehl mit Administratorrechten auszuführen:

sudo pip install -U pip 

Aber, empfehle ich Ihnen nicht zu ändern/verschmutzen Ihre systemweite Python. Verwenden Sie stattdessen einen virtualenv:

virtualenv myapp 
source myapp/bin/activate 
pip install -U pip # <- only if virtualenv is not up to date
