I am trying to run the official helloworld program in google-appengine 1.6.4 for python

  • 0

I am trying to run the official helloworld program in google-appengine 1.6.4 for python 2.7.

It’s so frustrating to be not able to run a simple helloworld. I would appreciate any kind of help here.

Error I encounter:-

    One difference between the files that you have on github and the official google hellworld tutorial is that your helloworld file doesn’t seem to be named helloworld.py. Potentially that would help?

    Additionally, do you need that PROJECT_DIR variable at the top of helloworld?

    If you are struggling to get the basic tutorial working, the first thing you should do is make sure that your project is literally the exact same as the google example.
