当我运行python manage.py runserver时，我的Django应用程序没有出现任何错误，但在完全设置后仍然没有运行。下面是错误日志的追溯。
class APIView(View):
File "/opt/formshare/lib/python2.7/site-packages/rest_framework/views.py", line 88, in APIView
authentication_classes = api_settings.DEFAULT_AUTHENTICATION_CLASSES
File "/opt/formshare/lib/python2.7/site-packages/rest_framework/settings.py", line 197, in __getattr__
val = perform_import(val, attr)
File "/opt/formshare/lib/python2.7/site-packages/rest_framework/settings.py", line 149, in perform_import
return [import_from_string(item, setting_name) for item in val]
File "/opt/formshare/lib/python2.7/site-packages/rest_framework/settings.py", line 165, in import_from_string
raise ImportError(msg)
ImportError: Could not import 'formshare.libs.authentication.DigestAuthentication' for API setting 'DEFAULT_AUTHENTICATION_CLASSES'. ImportError: No module named related.
