A few months ago I was working on a test GAE app. I was able to start the launcher and open the browser both on the app port and on the SDK Console port, and they both were working well.
Then I installed CherryPy, I created a CherryPy app, and I was able to browse to the app.
Today I restarted the GAE launcher. When I browse to my app page everything works well, while browsing to the SDK Console it shows the correct content, but doesn't show the static files.
The log mentions CherryPy.
Is the CherryPy I installed conflicting with GAE?
Does GAE use CherryPy (and my installation has nothing to do with it)?
How do I fix it?
For example when I browse to http://localhost:8002/assets/common.css (which is the css used by the SDK Console) I get the following log:

There is a bug in the GAE Windows static file handling. It has been documented here:
Google App Engine: Won't serve static assets with below error:
Reported to be fixed by updating from Python 2.7.7 to 2.7.8. Otherwise, you will want to explicitly specify the MIME types for your static files in app.yaml, as shown on that linked page.

Open %APPDATA%\Thonny\configuration.ini (or wherever your IDE config is)
Scroll down to [run] section and check parameter working_directory.
Make sure something meaningful is set there, e.g. C:\ should do the trick (no double backslahes, quotes, etc..).
I had the same issue. For some reason only word lib was there. Modifying this parameter to a proper filesystem path fixed it in my case.
Something has corrupted the current instance of your Thonny installation at the backend.
You will first need to completely uninstall Thonny and then remove any imprints of Thonny from your computer's registry.
Then reinstall Thonny and open Thonny IDE.
Hope this helps.
I also faced this issue, for me it was due to Antivirus, just disabling Auto Containment fixed the issue, Hope this helps.
This image will help you to find the issue I have configured Openstack newton on ubunu 16.04 LTS. It works fine
Now i have planned to integrate Murano in to this.
All progressed fine..When i am running dashboard using "tox -e venv -- python manage.py runserver <IP:PORT>" command. I am able to run the murano dashboard.
When i am accessing environment tab it displaying error
Error: There was an error communicating with server.
And log message displays an error

Can someone help on this?
Thanks in Advance.
Just installing memcached is not enough. You will also need to install python memcache module which is provided separately by python-memcache and python-pymemcache. I am not sure which one is used here.
You can try installing them with apt-get and see which one works for you.
Now working.. I have installed murano api and murano dashboard in different venv.
I have missed to install memcache in munano api venv. When i'm tried after install memcache in murano api venv..Now working fine..
#tutuDajuju Thanks for the Help...
I followed the tutorial on https://developers.google.com/appengine/docs/python/gettingstartedpython27/introduction (up to and including step 8). All runs well except that the app is displayed only partially (login feature doesn't show, no layout) when I view the uploaded version (guestbookruud.appspot.com) or the local version using the Browse button of the Google App Engine Launcher (showing port 13080). Only if I view the app locally through port 8080 all shows as intended.
What is wrong and how to solve?
Question update:
Browse button from the Launcher now gives a HTTP500 error. Here's the log (local):

OperationalError: database is locked
Found it, I was working in a different project directory than the one I was uploading from; though rather stupid this explains what was going on...
I'm using Google App Engine for the first time and I'm sort of confused about this error, I can't understand how to debug this any further.
I created an application under my account, then I'm trying to upload a python file into it via Google App Engine Launcher. But I keeping getting this error.

You can close this window now.
How do I debug this further? Seems like urllib2 is having problems with HTTPS. But that's strange because I'm not behind any local proxy and I've never had any other HTTPS problems.
I faced the same issue. I closed the Google App Engine Launcher and started it again, and attempted uploading the app, it worked.
I encountered the same problem. It does not work even I try different different PCs, operating systems, updating the latest SDK, or other solutions. I doubt that it is the problem of the Google App Engine Server side. After waiting for one day, everything is fine. So if you have the same problem, it may be a good choice to wait for one day.
I'm trying to set up a virtualenv for local development using Google App Engine and django-nonrel. I'm only trying to run the test app provided by django-nonrel for now.
The first time I tried, I got python manage.py runserver to work, but as soon as I tried to fetch a page from localhost:8080, it errored out on me, saying it couldn't find the pdb module:

I tried copying modules from my main Python installation, and I also tried creating a new virtualenv which had access to site-packages. Both approaches worked up to a point - python manage.py runserver ended up not being able to find urllib.
On the other hand, python manage.py shell and then e.g. import pdb or import urrlib (or any other standard library, for that matter) work fine. What am I supposed to do?
The solution: don't use virtualenv at all, and put the libraries you're going to need (such as django) in your project directory. You're going to need that to deploy your app to GAE, anyway.
