Question

I wanted to log what happened with my Django app on my test server so I’ve installed Django Sentry.

I’ve done everything as it is in the Quickstart guide from the official documentation but when I try to initialize the web service this error appears:

sentry.conf.py start

Thanks for your help!

Answer 1

gunicorn requires Python 2.6 – which added the except T as e syntax (see http://www.python.org/dev/peps/pep-3110/). You’ll need to switch to at least Python 2.6.

Note that in some places the documentation for gunicorn says it supports Python 2.5, but that is no longer true.
