How to appcfg rollback my project?

Question

I am using Google App Engine to upload my python project However once I try to upload my project I receive this error:

2013-07-24 20:21:06 Running command: "['C:\\Python26\\python.exe', '-u', 'C:\\Program Files\\Google\\google_appengine\\appcfg.py', '--no_cookies', u'[email protected]', '--passin', 'update', 'C:\\Users\\Thomas Stone\\Documents\\proxy-server']"

Another transaction by user Thomasston54321 is already in progress for app: s~mathsonlinegames, version: secureable. That user can undo the transaction with "appcfg rollback".

You can close this window now. 

Because of this I have tried this in CMD:

cd C:\Program Files\Google\google_appengine
appcfg.py rollback C:\Users\Thomas Stone\Documents\proxy-server

But then I receive this error in CMD

Usage: appcfg.py [options] rollback <directory> | <file>

appcfg.py: error: Expected a single <directory> or <file> argument.

Answer 1

You need to cd into the src folder.

Then do:

appcfg.py --no_cookies [email protected] --passin rollback ./

That always does the trick for me.

Answer 2

If you are unsuccessful trying above steps, place your app.yaml inside C:\Program Files\Google\google_appengine.

Then run:

C:\Program Files (x86)\Google\google_appengine>appcfg.py --no_cookies --email=Youremail --passin rollback app.yaml

It worked for me.

Answer 3

Using the command line GO to the location where google_apengine folder is present in my case it C:\Program Files (x86)\Google\google_appengine.

appcfg.py --no_cookies --email=yourEmail  rollback [ project_dir\]app.yaml 

in my case [project_dir="E:\practiceCode\wp_test"]

so command should be

appcfg.py --no_cookies [email protected]  rollback E:\practiceCode\wp_test\app.yaml

and you get the authentication verification and complete that and rollback done.
