Topic: ExtractionError: Can't extract file(s) to egg cache

[mophilly]

I am writing a How-To for installing Django on SME 7.1.1. If I can succeed with this, I may try my hand at building an rpm for SME.

I have a freshly made server, and have made pretty good progress so far.  The framework is responding; mod_python is working. Still having a couple of problems.

When connecting to mySQLdb via Django framework, I am getting a permissions error; see subject line. Python trace back follows.

Permissions are root:wheel 770 for /.python-eggs in /root/.python-eggs. I assume that is the right location.

Any ideas on how can I resolve this?

ExtractionError: Can't extract file(s) to egg cache

The following error occurred while trying to extract file(s) to the Python egg
cache:

  [Errno 13] Permission denied: '/.python-eggs'

The Python egg cache directory is currently set to:

  /.python-eggs

Perhaps your account does not have write access to this directory?  You can
change the cache directory by setting the PYTHON_EGG_CACHE environment
variable to point to an accessible directory.

After a few hours of stumbling around the web I found solution. It is simple, which is always good.

Brett Neumeier posted a solution on the trac list at gossamer-threads. His solution was to move the egg to a zip file, create directory with the same name as the egg and unzip the egg contents into the directory.

I am not certain this is cool for a production SME server but it worked like a charm. Thanks to Brett for the great idea.

Hello Mophilly,
can you please post how you got MySQL for Python installed?

Thanks.

I got mysql-python working.

installed mysql-devel and built an RPM from the source of mysql-python.

Thanks
