Errno 13 Zugriff verweigert: '.cache' Django App?

Question

Ich stelle eine Django-App auf Ubuntu Server 14.04 bereit und konnte erfolgreich die IP-Adresse in meinem Browser erreichen. Jetzt bekomme ich jedoch einen Django-Debugfehler, der mit "[Errno 13] Berechtigung verweigert: '.cache'" bezeichnet wird. Ich bin mir nicht sicher, was das bedeutet. Der Weg, den die App erstickt, ist '/usr/lib/python3.4/os.py', was mir seltsam erscheint, weil ich eine virtuelle Umgebung benutze, die nicht in diesem Verzeichnis ist, um die Python-Version zu erstellen und Abhängigkeiten. Jede Hilfe würde wirklich geschätzt werden. Mir ist klar, dass viele Leute das gleiche Problem hatten, aber ich habe keine einzige gute Lösung gefunden. Ich bin nicht auf der Suche nach einer Lösung, die nur alle Berechtigungen für ein bestimmtes Verzeichnis erlaubt; Ich möchte bei der Anwendung dieses Fixes ein gutes Sicherheitsniveau beibehalten. Danke im Voraus.

Answer 1

Hier ist Ihr Fehler:

File "var/www/html/scheduler.marist.edu/sched_app/sched_app/views.py", line 131, in 
    [Wed May 18 20:42:24.837054 2016] [:error] [pid 6078:tid 139663218018048]  h = httplib2.Http(".cache") 

Das hat nichts mit django-Caching, wie ich (und wahrscheinlich auch fast alle anderen, die dies lesen) tun soll. Es ist mit Ihrer Verwendung von zu tun.

Kommentieren Sie diesen Abschnitt des Codes und Sie können starten.

Aktualisieren. Ich bin kein Experte für httplib2, aber was ich gerade gelesen habe, ist, dass ".cache" das Verzeichnis angibt, in dem httplib2 Seiten cachen wird, die es abrufen wird. Wenn Sie diesen Parameter nicht übergeben, wird nichts zwischengespeichert. Möglicherweise möchten Sie hier einen sicheren, aber schreibbaren Pfad verwenden, wenn Sie das Caching aktivieren möchten.
