Importfehler beim Bereitstellen der Django-App für Heroku

Question

Ich versuche, die App, die sie erwähnt haben, im Abschnitt "Erste Schritte" bereitzustellen. Allerdings bekomme ich Fehler ModuleNotFoundError: No module named 'six'. Das gesamte Erstellungsprotokoll ist unten erwähnt:

Ich habe sogar das six Modul installiert, aber es funktioniert nicht.

Answer 1

Sie (alongwith mit vielen anderen) stehen vor this issue

upgrade your CI environment to just short of v36 with the following pre-install command:

pip install --upgrade "setuptools < 36" 

Dann werden durch sicherzustellen, dass Ihre virtualenv bald zu erstellt wird geerbt diese Version mit den folgenden Umgebungsvariablen:

VIRTUALENV_NO_DOWNLOAD=1 

Eine andere Lösung ist durch die Installation des Moduls sixvor Ausführen eines anderen Befehls.

Die offizielle Antwort in der Github Repo war, dass es so schnell wie möglich behoben wird. Ich hoffe, es funktioniert. Prost!
