Ich versuche installieren Heroku zu bekommen psycopg2 von requirements.txt zu installieren, die enthält:Heroku nicht psycopg2
falcon
gunicorn>=19.6.0
gevent>=0.13
ujson
SQLAlchemy
alembic
psycopg2
Diese im folgenden Buildprotokoll ergibt:
-----> Python app detected

Dies scheint darauf hinzu befolgen Sie den Herokus-Leitfaden zur Verbindung mit PostgreSQL über Python (https://devcenter.heroku.com/articles/heroku-postgresql#connecting-in-python), ich kann jedoch keine Lösung für dieses Problem finden.
Warum verwenden Sie zwei Datenbanken SQLAlchemy und postgreSQL. Probieren Sie es mit nur einem in requirements.txt aus. –
@RajanChahan SQLAlchemy ist ein ORM und verwendet psycopg2, um eine Verbindung mit dem spezifischen Datenbankserver herzustellen (in diesem Fall pgsql). –
