Google App Engine Python 2.7教程错误

Question

I am following Google App Engine "Hello world" tutorial in this link: https://developers.google.com/appengine/docs/python/gettingstartedpython27/helloworld

I want to load my helloworld.py application:

import webapp2

class MainPage(webapp2.RequestHandler):
  def get(self):
      self.response.headers['Content-Type'] = 'text/plain'
      self.response.out.write('Hello, Udacity!')

app = webapp2.WSGIApplication([('/', MainPage)],
                              debug=True)

And I set the yaml file:

application: helloworld
version: 1
runtime: python27
api_version: 1
threadsafe: true

handlers:
- url: /.*
  script: helloworld.app

I am not using Google App Engine Launcher, just want to do everything in the console or command line.

I want to start my helloworld app using dev_appserver.py --port=8888 helloworld , but the console complains AppConfigNotFoundError . The console outputs

C:\Documents and Settings\XXX\Desktop\helloworld>dev_appserver.py --port=8888
 helloworld

v_appserver.py", line 3217, in LoadAppConfig
    raise AppConfigNotFoundError
google.appengine.tools.dev_appserver.AppConfigNotFoundError

Would this be a path problem? My helloworld.py and app.yaml is in a folder on my desktop and not in the google app engine directory.

How can fix this error? Any suggestion is appreciated!

Note: I am using Python 2.7 NOT 2.5.

Answer 1

When you call dev_appserver.py , the last argument should be the path to the directory that your app.yaml is in. In your case, since you are running from within your project's directory, you can just use dev_appserver.py --port=8888 . , because . is short for the current directory.
