sudo easy_install --upgrade schemaobject
If you installed SchemaObject using setup.py install, you can upgrade by deleting the SchemaObject directory from your Python site-packages (or virtualenv) and re-installing the new version.
Where are my site-packages stored?
The location of the site-packages directory depends on the operating system, and the location in which Python was installed. To find out your system’s site-packages location, execute the following:
python -c "from distutils.sysconfig import get_python_lib; print get_python_lib()"
Note that this should be run from a shell prompt, not a Python interactive prompt. Thanks to the Django install page for these helpful instructions.
