Google app engine dev_appserver.py problems

I'm just starting with google app engine and I followed the basic hello world example on google app engine.

https://developers.google.com/appengine/docs/python/gettingstartedpython27/helloworld

created both files in the helloworld folder.

I don't want to use the GUI I prefer to use the mac terminal to work with this application. I want to start this application on my local host localhost:80 through the terminal.

to run my basic helloworld application locally all I say is

$ dev_appserver.py helloworld . but I get this error.

Traceback (most recent call last):
  File "/usr/local/bin/dev_appserver.py", line 184, in <module>
    _run_file(__file__, globals())
  File "/usr/local/bin/dev_appserver.py", line 180, in _run_file
    execfile(script_path, globals_)

    main()
  File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/tools/devappserver2/devappserver2.py", line 720, in main

    with open(configuration_path) as f:
IOError: [Errno 2] No such file or directory: 'helloworld'

I have two files in the helloworld directory. app.yaml

application: your-app-id
version: 1
runtime: python27
api_version: 1
threadsafe: true

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

and the helloworld.py

import webapp2

class MainPage(webapp2.RequestHandler):

    def get(self):
        self.response.headers['Content-Type'] = 'text/plain'
        self.response.write('Hello, World!')


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

Create a directory test-dir

Extract google-cloud-sdk in this directory

Inside test-dir directory create another directory 'helloworld'

After creating both files from https://webapp2.readthedocs.io/en/latest/tutorials/gettingstarted/helloworld.html#tutorials-gettingstarted-helloworld in helloworld directory

In terminal:

Go to test-dir directory

Run: google-cloud-sdk/bin/dev_appserver.py helloworld/

From the directory ...\Google\Cloud SDK\google-cloud-sdk\bin :

Instead of :

dev_appserver.py YOUR_DIRECTORY

Try :

py dev_appserver.py YOUR_DIRECTORY

Or :

python dev_appserver.py YOUR_DIRECTORY

After installing the google cloud sdk, did you run 

gcloud components install app-engine-go

The documentation is kind of ridiculous in terms of organization. I totally missed this when I first started

  1. When you first launch Google App Engine, a prompt asks if you want to make "Command Symlinks" -- be sure to click OK, then enter the administrator password. That is what enables you to use symbolic links in the /usr/local/bin folder for the command dev_appserver.py.

  2. Enter the following into the terminal (command-line) 

    $: /usr/local/bin/dev_appserver.py helloworld

Here's an example what my browser, terminal, and finder windows look like.

For reference, here is an O'Reilly guide to installing/running google app engine on mac.

  1. To shut down the web server, make sure the terminal window is active, then press Control-C

I had the same problem. After some effort the command that worked for me, inside the google_appengine directory and not in the helloword dir is:

python dev_appserver.py helloworld/

maybe this helps.
