How to setup up PYTHON_EGG_CACHE environment variable on Mac?

问题

I am trying to setup Django to use MySQL. I am getting the following error when I type in localhost/mysite

ExtractionError at /
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: '/Library/WebServer/.python-eggs'

The Python egg cache directory is currently set to:

  /Library/WebServer/.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.

From the error message I know that I have to change the PYTHON_EGG_CACHE environment variable to point to a directory that Apache can access. I tried adding the following to httpd.conf

SetEnv PYTHON_EGG_CACHE /var/www
<Directory /var/www>
    Order deny,allow
    Allow from all
</Directory>

and also just SetEnv PYTHON_EGG_CACHE /var/www to bashrc, but nothing seems to resolve the problem. Any suggestions on what I might be doing wrong?

Note: www is a folder that I created

回答1:

Also might try to set the egg cache directory in the wsgi script,

import os
os.environ['PYTHON_EGG_CACHE'] = '/usr/local/pylons/python-eggs'

as can be found from here http://code.google.com/p/modwsgi/wiki/ApplicationIssues

Based on your previous question, you're using WSGI. You want WSGIPythonEggs or the python-eggs option for WSGIDaemonProcess.
