The configuration nginx + flup + django or the django runserver don't seem to create the conditions for the error. Basically I am seeing an error > Traceback (most recent call last): > File "./project/fundfacts/api.py", line 33, in refresh_data > call_command('fe_data_load', month=period_id, datadir=upload_dir) > File "/home/rptlab/website/quilter.reportlab.com/quilter_2/lib/python2.7/site-packages/django/core/management/__init__.py", line 105, in call_command > command = load_command_class(app_name, name) > File "/home/rptlab/website/quilter.reportlab.com/quilter_2/lib/python2.7/site-packages/django/core/management/__init__.py", line 40, in load_command_class > module = import_module('%s.management.commands.%s' % (app_name, name)) > File "/usr/lib/python2.7/importlib/__init__.py", line 37, in import_module > __import__(name) > ImportError: No module named fe_data_load some hack printouts along the error path seem to indicate that the import should be possible as executing module = import_module('%s.management.commands.%s' % (app_name, 'fe_data_load')) in the manage.py shell work fine and sys.path looks as expected. The uwsgi worker process (I'm forking) is corrupted after (or perhaps because of ) this error and causes previously working pages to fail; it looks like the python interpreter's gone wrong somehow. Any good ways forward with debugging this sort of issue? I'm not sure how I would remotely debug this using winpdb. -- Robin Becker
