$ git clone git@github.com:prerit2010/Result-aggregation-server.git && \
cd Result-aggregation-server && \
python manage.py db init && \
python manage.py db migrate && \
python manage.py db upgrade

I got

alembic.util.exc.CommandError: Can't locate revision identified by 'bea6982d2a4e'

@rgaiacs You already had a db named result_aggregation.db in your home directory.

python manage.py db migrate command creates a database if it's not already there and then updates the schema in migrations. But as it found a db present, it did not find the alembic revisions of db in its migrations. So to start fresh, db needs to be deleted as well.

[HiIcy]

thanks to @prerit2010 ,I have solved the issue yet
