When I create a Python module with the Google App Engine facet, everything seems to work as far as compiling an app and deploying it to Google. However, I can't seem to get the local development server to work. A run configuration is automatically set up when I first create the Python module but it shows a red X on the congifurationand when it is run I get "Cannot find Python interpreter for this run configuration". Editing the configuration shows this message: "Run Configuration Error: Please select a valid Python interpreter" (see attached image). However, I have specified an interpreter for the Python module and I can run python scripts in this module without a problem. Where do I select a valid Python interpreter as requested by the App Engine Server run configuration?
