if it might be caused by wsgi.py configuration issues in pythonanywhere, in local env, django handles python path and static files. According to this part in pythonanywhere deploy doc:

  • adding correct sys.path to wsgi.py
if your Django settings file is in / home / my _username / projects / my_project / settings.py ' 
path = '/home/my_username/projects'
if path not in sys.path:
    sys.path.append(path)
os.environ['DJANGO_SETTINGS_MODULE'] = 'my_project.settings'
from my_project.myapp.models import Kitchen, Sink

note: the prefix my_project is required.



2.static files should handle well

from django.contrib.staticfiles.urls import staticfiles_urlpatterns
urlpatterns += staticfiles_urlpatterns()

check that these two points according to the doc should fix it.

Having the same problem with my app ... the problem turned out to be a file problem. If the application directory does not have execute permissions, it could not be imported.
