设置Apache和Python WSGI以使用VirtualEnv

Question

我无法让Apache/WSGI使用我的VirtualEnv.我在我的WSGI文件中添加了以下两行(服务器上的路径指向目标virtualenv中site-packages的实际位置):

import site
site.addsitedir('/sites/mysite/virtpy/lib/python2.6/site-packages')

(来自http://www.foxhop.net/django-virtualenv-apache-mod_wsgi).但是,当我尝试在浏览器中加载url时,我得到500.检查apache日志:

 [Sun Jul 17 11:07:11 2011] [error] [client 94.170.105.142]     app =   import_module(appname)
[Sun Jul 17 11:07:11 2011] [error] [client 94.170.105.142]   File "/usr/local/lib/python2.6/dist-packages/django/utils/importlib.py", line 35, in import_module

所以我猜VirtualEnv没有被加载.任何人都知道如何告诉Apache/WSGI使用正确的virtualenv？

UPDATE

我按照Ken的建议更新了django.wsgi,但现在我在apache日志中收到以下错误

[Sun Jul 17 16:46:36 2011] [info] [client 94.170.105.142] mod_wsgi (pid=11260, process='', application='igniteflow-django.com:8090|'): Loading WSGI script '/sites/igniteflow/apache/django.wsgi'.

我认为这是因为virtualenv在root中而apache没有权限？我将文件夹归为root:www-data,但它没有解决问题.有什么建议？

在我的app.wsgi文件中,我有类似的东西.您需要将其更改为放置到虚拟环境所在的位置,在此示例中,我的位于/ opt/ve/ve_name /下.

import os
# activate virtualenv
activate_this = os.path.expanduser("/opt/ve/ve_name/bin/activate_this.py")
execfile(activate_this, dict(__file__=activate_this))
