I am following the tutorial, https://developers.google.com/appengine/docs/python/gettingstartedpython27/helloworld. I use Ubuntu 12.04

I prepared the helloworld example and then I got this message:

mark@einstein:~/Desktop$ google_appengine/dev_appserver.py ~/googleapps/helloworld/

You can port your existing data using the --port_sqlite_data flag or
purge your previous test data with --clear_datastore.

What should I do to get it working?

those warnings are "normal". Can you reach it on localhost:8080 –  Paul C Feb 13 '13 at 16:21
That was it, I just realised my 'problem' was at a really basic level: I didn't realize I could see the output at http://<<lch>>:8080 in my browser (<<lch>> stands for an illegal word on this forum: 'l0calh0st') I hope this helps someone else with very early starting up problems ;-) –  user65410 Feb 13 '13 at 22:46

This question came from our site for professional and enthusiast programmers.

Install MySQL (if not already)

and then Python MySQLdb

see instructions here:

as Paul C notes in a comment, the warnings are normal, the SDK is working fine, you just can't use the 'Google Cloud SQL' APIs without MySQL up and running

Thank you for your answer, I have installed mysql-pythondb now. sudo apt-get install python-mysqldb. –  user65410 Feb 13 '13 at 22:40
did it get rid of the warnings? –  Anentropic Feb 14 '13 at 12:41
Hi Anentropic, sorry for the late reaction, I just saw your question. The first warning disappeared (rdbms_mysqldb.py:74] The rdbms API is not available because the MySQLdb library could not be loaded.) Otherwise it seems to be working alright. –  user65410 Feb 25 '13 at 21:49
