python flask app mod_wsgi / apache

Question

I'm working on getting my python flask app on my linode server. I've followed a few tutorials to get this configured, but am stuck because when I visit the url, i get this error. "ImportError: No module named ugpromo". I've seen other problems like this on stackoverflow, and have tried their solutions, but I still get the same error.

You've added the outer "ugpromo" directory - the one containing the __init__ file you want to import - to your sys.path. You need to add the parent of that directory instead:

sys.path.insert(0,"/var/www/html/codingbybrandon/public_html/")

(Note, however, you really shouldn't be putting code under public_html. Place it somewhere else.)
