如何在Mac上设置PYTHON_EGG_CACHE环境变量？ [英] How to setup up PYTHON_EGG_CACHE environment variable on Mac?

问题描述

我正在尝试设置Django来使用MySQL。当我输入 localhost / mysite

 时，我收到以下错误/ 
中的ExtractionError无法将文件提取到egg cache 
 
尝试将文件解压缩到Python egg 
缓存时出现以下错误：
 
 [Errno 13]权限被拒绝：'/Library/WebServer/.python-eggs'
 
 Python egg缓存目录目前设置为：
 
 /Library/WebServer/.python-eggs 
 
也许您的帐户没有这个目录的写入权限？您可以
通过将PYTHON_EGG_CACHE环境
变量设置为指向可访问的目录来更改缓存目录。 
  

从错误消息中我知道我必须更改 PYTHON_EGG_CACHE 环境变量指向Apache可以访问的目录。我尝试将以下内容添加到 httpd.conf

  SetEnv PYTHON_EGG_CACHE / var / www 
< Directory / var / www> 
订单拒绝，允许
允许从所有
< / Directory> 
  

还只是 SetEnv PYTHON_EGG_CACHE / var / www 到 bashrc ，但似乎没有解决问题。关于我可能做的错误的任何建议？

注意： www 是我创建的文件夹

解决方案

也可能尝试在wsgi脚本中设置egg缓存目录，

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

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
解决方案
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
