Psycopg2 auf elastischen Bohnenstange - kann keine App

Question

Ich bin die Bereitstellung meiner ersten App (Flask) zu EB und bin ein Haken. Die Verwendung von PostgreSQL erfordert, dass ich psycopg2 installiert habe, aber ich kann nicht herausfinden, wie es funktioniert.

sah ich in diesem Beitrag (Psycopg2 on Amazon Elastic Beanstalk) sowie diesen Beitrag (https://realpython.com/blog/python/deploying-a-django-app-to-aws-elastic-beanstalk/), die ich brauche einen Dateinamen .elasticbeanstalk/01_packages.config mit dem folgenden Code hinzuzufügen:

packages: 
    yum: 
    postgresql-devel: [] 

ich verschiedene Varianten mit postgresql93-devel: [] versucht haben und immer noch kein Glück. Anbei finden Sie meine Fehlerprotokolle.

Es scheint ziemlich klar, dass ich brauche psycopg2 installiert zu bekommen, aber ich bin mir nicht sicher, was andere Schritte, die ich nehmen kann diese Arbeit zu machen.

Answer 1

ich es gelöst, müssen Sie Sie EC2-Instanz öffnen zuerst, dann wie dieses

sudo yum install postgresql-devel 

Dann implementieren Ihre EB installieren

Answer 2

Auch nach postgresql93-devel installieren, hielt ich erhalte eine Fehlermeldung „no Modul namens psycopg2 ". Um dies zu lösen, musste ich eine Verbindung zu meiner Umgebung mit eb ssh herstellen und dann sudo pip install psycopg2 ausführen, um dies zu lösen.
