Django Heroku Postgres collectstatic --noinput

Question

Ich habe Probleme, meine Django 1.10 App auf Heroku zu bekommen. Wenn ich diese Seite zu Heroku schieben, erhalte ich die Anwendungsfehler:

ProgrammingError at /homelibrary/ 
relation "catalog_book" does not exist 
LINE 1: SELECT COUNT(*) AS "__count" FROM "catalog_book" 

Seit ich die Standard-Sqlite3 Datenbank Postgres geändert, es war nicht lokal ausgeführt und ich bekomme Fehler jedes Mal, wenn ich wandern. Ich habe versucht:

python3 manage.py makemigrations 
python3 manage.py makemigrations catalog 
python3 manage.py syncdb 
python3 manage.py migrate catalog --fake 
python3 manage.py migrate --fake 

ich diesen Fehler jedes Mal: ​​

Traceback (most recent call last):

Manchmal habe ich Variationen in der letzten Zeile, wie

django.db.migrations.exceptions.NodeNotFoundError: Migration catalog.0003_book_sub_title dependencies reference nonexistent parent node ('homelibrary', '0002_auto_20170107_2158') 

und

django.db.migrations.exceptions.NodeNotFoundError: Migration catalog.0006_auto_20170107_2320 dependencies reference nonexistent parent node ('homelibrary', '0005_auto_20170107_2300') 

Hat jemand irgendwelche Vorschläge, was ist g? falsch?

UPDATE:

ich mit allen Migration Dateien gelöscht:

find . -path "*/migrations/*.py" -not -name "__init__.py" -delete 
find . -path "*/migrations/*.pyc" -delete 

Jetzt bin ich nicht in der Lage zu Heroku Master schieben und eine Fehlermeldung erhalten, dass/tmp/build_e7c89faecaf0e6bc9724a9a2be271ba4/static existiert nicht :

Versuchen Sie, jede Migration einschließlich Abhängigkeiten separat ausgeführt werden.

python manage.py migrate auth 
python manage.py migrate sites 
python manage.py migrate <your-app> 

Ich konnte einige Probleme wie diese umgehen.
