在使用MySQLdb包后，導入測試時發現一個警告。
/usr/lib/python2.6/site-packages/setuptools-0.8-py2.6.egg/pkg_resources.py:1054:
UserWarning: /home/sgpromot/.python-eggs is writable by group/others and vulnerable
to attack when used with get_resource_filename. Consider a more secure location
(set with .set_extraction_path or the PYTHON_EGG_CACHE environment variable).
warnings.warn(msg, UserWarning)
解決方法：
