Troubleshoot TemplateNotFound error from Flask under Gunicorn

Question

I\'ve got a Flask app that I\'m trying to deploy using Gunicorn and nginx. However, although it works fine locally, it throws a TemplateNotFound error when I run in with Gunicor

Answer 1

Are your templates in [app root]/templates/?

If so, check to be sure your path is correct. Put this as the first line in the view that handles your homepage:

return app.root_path

If that's what you expect to see - or if you're using Blueprints or another method that changes the default Jinja Environment somehow - it's a little more complicated.

Oddly, Jinja doesn't seem to have a jinja2.Environment.FileSystemLoader.get_search_path() method. I assumed it would have one :(
