如何在Mac上設置PYTHON_EGG_CACHE環境變量？

Question

我想設置Django來使用MySQL。我收到以下錯誤，當我在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. 

鍵入從我知道我必須改變PYTHON_EGG_CACHE環境變量指向Apache可以訪問目錄的錯誤消息。我嘗試添加以下到httpd.conf

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

，也只是SetEnv PYTHON_EGG_CACHE /var/www到bashrc，但似乎沒有任何解決問題。有關我可能會做錯什麼的建議？

注：www是我創建

也可能會嘗試蛋定高速緩存目錄中的WSGI腳本，

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

如可以從這裏 http://code.google.com/p/modwsgi/wiki/ApplicationIssues

根據你前面的問題，您正在使用WSGI的文件夾。您需要WSGIPythonEggs或python-eggs選項WSGIDaemonProcess。
