Just upgraded to Ubuntu 13.04 and Eclipse complained with the following 2 errors:

1. ImportError: No module named _sysconfigdata_nd

ERROR    2013-03-25 07:26:43,559 http_runtime.py:221] unexpected port response from runtime ['']; exiting the development server
ERROR    2013-03-25 07:26:43,561 server.py:576] Request to '/_ah/warmup' failed

2. dev_appserver.py: error: unrecognized arguments: --high_replication

I've never encountered the first one. And for the second, I used to run google app engine applications by setting the --high_replication argument and it worked well. Why all the sudden, these two didn't work? Thanks in advance.

Did you upgrade to the 1.7.6 SDK? Some of the commandline parameters changed, I believe high_replication is on by default. - dragonx
Yes, the version is 1.7.6. Thanks for clarifying that, dragonx. In addition, do you have any idea about the first error? - Randy Tang
No clue about the first one, it's probably something with your system setup. I just grepped through the SDK and there's no reference to _sysconfigdata_nd. - dragonx
I think that was a bug because if I used old_dev_appserver.py instead, everything was fine. I have filed a bug report. Thanks a lot. - Randy Tang

The "No module named _sysconfigdata_nd" is a bug in the Ubuntu package.

You can create a softlink as a workaround:

sudo ln -s /usr/lib/python2.7/plat-*/_sysconfigdata_nd.py /usr/lib/python2.7/

Depending on different conditions, updating virtualenv may actually be a better idea instead of this walkaround, as mentioned on linked bug reports. To update virtualenv you could use the following command:

sudo pip install --upgrade virtualenv
