app engine python tutorial error

Question

I'm trying to do the python tutorial here http://code.google.com/appengine/docs/python/gettingstarted/helloworld.html

(I have python 2.5 installed)

After creating the python and yaml files I used the app engine launcher to run the code. Then I checked localhost:8080 and received the following error:

<class 'google.appengine.tools.dev_appserver.AppConfigNotFoundError'>   Python 2.5: C:\Python25\pythonw.exe

A problem occurred in a Python script. Here is the sequence of function calls leading up to the error, in the order they occurred.

any ideas?

Answer 1

For me, I solved this problem by adding the path to where the "app.yaml" file is located under the "Arguments" tab of the "Debug Configurations" dialog:

Answer 2

The AppEngine SDK is complaining because it can't find its own configuration file. Try reinstalling using the MSI provided on the Google AppEngine site.
