Openstack-Dashboard gibt internen Serverfehler

Question

Wenn ich versuche, das Dashboard zu öffnen, gibt es einen internen Serverfehler. Es lief früher gut, aber plötzlich trat dieser Fehler auf.

Hier ist mein Apache-Log:

Answer 1

Wenn Sie Google für diesen Fehler, erhalten Sie eine bug report auf Launchpad, mit einem langen weitläufigen Satz von Kommentaren finden. Der letzte sagt:

From the responses here it seems that the root issue with those encountering this "bug" is that their Horizon installation is missing some dependency, and installing that dependency fixes the issue.

The error reported "ImportError: cannot import name base" is a symptom of the failure to load all dependent modules.

The cause therefore would appear to be incomplete or erroneous installation documentation.

(Oder vielleicht ... Nichtbeachtung der Installationsanweisungen folgen.)

Kurz gesagt, prüfen Sie, ob Sie die richtigen Versionen der alle Abhängigkeiten für Horizon installiert haben.

Eine zweite bug report kann weitere Hinweise bieten.

Sie sagen:

It was running fine earlier but suddenly this error occurred.

Das zurückzuführen sein könnte aktualisieren/Patch angewendet wird.
