Try running from the directory
$(venv)/XXXXX/books.archivelab.org/books.archivelab/

ie : $.(venv)/XXXXX/books.archivelab.org/books.archivelab/   ls
(api  app.py  configs  __init__.py  __pycache__  static  templates  views)

Try running using the command:
$.(venv)/XXXXX/books.archivelab.org/books.archivelab/python app.py

I am unable to run using flask run command.

Also, Edited a file
books.archivelab/configs/__init__.py

'dbn': config.getdef('db', 'dbn', 'postgresql'),


# DATABASES
DB_URI = '%(dbn)s://%(user)s:%(pw)s@%(host)s:%(port)s/%(db)s
?client_encoding=utf8' % {
'dbn': config.getdef('db', 'dbn', 'postgresql'),
