HTTP Error 500 when attempting to access localhost

I just built my first "web app" for a class using Google App Engine, and it deployed correctly, and works perfectly well on Google's servers. However, when I try to access it on localhost, I get a 500 error:

"Server error The website encountered an error while retrieving http://localhost:8081/. It may be down for maintenance or configured incorrectly."

I have tried using various ports, and none of them seem to work. I am 100% positive I am using the correct port and that the app is actually running with no errors.

I am using Google Chrome and Python 2.7.2 on Mac OS 10.6.8

Any ideas on how to correct this or what configurations to check?

Turns out, the issue was that GAE was accessing an older version of python on my computer.

I was able to fix this by opening up the python launcher, copying the path from "Interpreter", and pasting it into GAE under Preferences/Python Path. In my case, the correct path is /usr/local/bin/pythonw

It is important to note that as there is no "ok" or "apply" button here, you must hit enter to apply the path change.

"Error 500" is generic for "I asked the server to do something, and it failed".

1) Look in your web server's error logs

2) Debug your "hello world" application

ALSO:

3) Make sure you can run this "hello world":

4) If you can't, then review the setup instructions here:
