virtualenv hängt vor dem Schreiben in den Fach

Question

Virtualenv hängt konsequent nach der erfolgreichen Installation von Pip, SetupTools und Rad. Ausführen virtualenv venv -v in meinem Home-Verzeichnis oder in einem anderen Verzeichnis auf dem VM gibt:

Es hängt hier, und nie gibt die folgenden Zeilen.

Writing venv/bin/activate.fish 
Writing venv/bin/activate_this.py 
Writing venv/bin/activate.csh 

Wenn ich Ctrl +C aus, es diesen Traceback spuckt, aber ich bin nicht sicher, ob es in die Ctrl +C oder dieser Frage in engen Zusammenhang steht.

Traceback (most recent call last):

Ich bin mit virtualenv Version 15.0.3, die ich von 15.0.1 aktualisiert this similar issue nach dem Lesen. Python ist Version 2.7.5. Die ganze Sache läuft auf Red Hat Enterprise Linux Workstation Version 7.2 (Maipo)

Es scheint wie Clearing pips Cache löst dieses Problem. Ich wünschte wirklich jemand wüsste warum, obwohl.
