dev_appserver.py doesn't recognize my files

Question

I'm trying to get a basic GAE tutorial to work with Windows 7.

So far I have:

1. Installed python 2.5.4
2. Installed the current GAE SDK
3. Set my PATH varible to include python and the GAE
4. Created a "hello, world" app with an app.yaml and main.py file as specified.

When I call dev_appserver.py . in my app's directory or dev_appserver.py DIRECTORY_NAME one directory above my app, I receive the error message:

Invalid arguments

Application root must be the path to the application to run in this server. Must contain a valid app.yaml or app.yml file.

[A bunch of dev_appserver.py option follow this]

What am I doing wrong? and as far as I can tell, I've correctly configured everything.

Answer 1

I had the same problem. Adding python.exe in front of dev_appserver.py solved the problem for me.

c:\Programme\Python27\python.exe C:\Programme\Google\AppEngineSDK\google_appengine\dev_appserver.py MoviesBwu\

Select any .py file press alt + enter(right mouse click -> properties) select change then choose python.exe(application) for opening .py file from install directory and run your file... ;-p
