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: '/root/.python-eggs'

The Python egg cache directory is currently set to:

  /root/.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.

解决方法：
在conf文件中添加："SetEnv PYTHON_EGG_CACHE /tmp"
