Google App Engine appcfg.py shows the help message for every command

Question

I have GWT app, which is deployed on GAE (Java). I\'m trying to download data from App Engine datastore using appcfg.py . I did all the setup according to http://ikaisays.com/20

Answer 1

The right way is to change the environment variables on Windows 7:

1. Go to System Properties
2. Go to Advance System Settings
3. Click on Environment Variables
4. Append to Path variable the values C:\Python27\
5. Click Ok and restart your computer. (Yes, it is needed.)

Another way is to:

1. Open command Prompt

2. Locate your python.exe file. For example:

   C:\Python27>_

3. Then, run a python command that looks like this.

   python <appcfg_directory> download_app -A <your_app_id> -V <your_app_version> <output-dir>

Where <appcfg_directory> is equal to C:\Program Files\Google\google_appengine\appcfg.py. (Depending on your file location)

Don't forget to put quotes before and after <appcfg_directory>

Answer 2

The following fix worked for me. It looks like appcfg.py doesn't like PYTHON27 and ALWAYS returns the help menu. I fixed it by executing it with PYTHON25 and hard coded all my file locations:

C:\Python25-archive\python "C:\Program Files (x86)\Google\google_appengine\appcfg.py" rollback C:\scripts\myapp
