django - Getting Started with Python on Heroku - Run the app locally step issue -
i following "getting started python on heroku" official tutorial. think tutorial setting django hello world, though have not seen outcome yet.
these steps worked:
$ git clone https://github.com/heroku/python-getting-started.git $ heroku create $ git push heroku master output last command (important part in opinion):
... remote: -----> python app detected remote: -----> installing runtime (python-2.7.9) remote: -----> installing dependencies pip remote: collecting dj-database-url==0.3.0 (from -r requirements.txt (line 1)) remote: downloading dj_database_url-0.3.0-py2.py3-none-any.whl remote: collecting django==1.8.1 (from -r requirements.txt (line 2)) remote: downloading django-1.8.1-py2.py3-none-any.whl (6.2mb) remote: collecting django-postgrespool==0.3.0 (from -r requirements.txt (line 3)) remote: downloading django-postgrespool-0.3.0.tar.gz remote: collecting gunicorn==19.3.0 (from -r requirements.txt (line 4)) remote: downloading gunicorn-19.3.0-py2.py3-none-any.whl (110kb) remote: collecting psycopg2==2.6 (from -r requirements.txt (line 5)) remote: downloading psycopg2-2.6.tar.gz (367kb) remote: collecting sqlalchemy==1.0.4 (from -r requirements.txt (line 6)) remote: downloading sqlalchemy-1.0.4.tar.gz (4.6mb) remote: collecting whitenoise==1.0.6 (from -r requirements.txt (line 7)) remote: downloading whitenoise-1.0.6-py2.py3-none-any.whl remote: installing collected packages: dj-database-url, django, psycopg2, sqlalchemy, django-postgrespool, gunicorn, whitenoise remote: running setup.py install psycopg2 remote: running setup.py install sqlalchemy remote: running setup.py install django-postgrespool remote: installed django-1.8.1 sqlalchemy-1.0.4 dj-database-url-0.3.0 django-postgrespool-0.3.0 gunicorn-19.3.0 psycopg2-2.6 whitenoise-1.0.6 ... further commands:
$ heroku ps:scale web=1 $ heroku open then procfile defined following line:
web: gunicorn gettingstarted.wsgi --log-file - then created virtualenv (tried both python 2.7.6. , 3.4.2):
$ virtual venv $ source venv/bin/activate $ pip install -r requirements.txt --allow-all-external first time around had problem psycopg2-2.6, believe installed. here requirements: - dj-database-url==0.3.0 - django==1.8.1 - django-postgrespool==0.3.0 - gunicorn==19.3.0 - psycopg2==2.6 - sqlalchemy==1.0.4 - whitenoise==1.0.6

i think there problem database configuration, new , find hard workout has happened debug log. have searched web trying find similar cases output of last command, did not find had exact same nature mine.
has experienced similar? please figure out it.
edit:
an additional step appeared in heroku tutorial since question asked.
run app locally step has following command now:
$ python manage.py collectstatic this line added before step got stuck:
$ foreman start web
based on error, django.core.exceptions.improperlyconfigured: 'django_postgrespool' isn't available database backend., appears database setting improperly configured.
in settings file, since you're using postgresql, make sure database engine set 'django.db.backends.postgresql_psycopg2'. see databases docs , database engine docs.
