django - 设置 Apache 和 Python WSGI 以使用 VirtualEnv

Question

我在让 Apache/WSGI 使用我的 VirtualEnv 时遇到问题。我已将以下两行(服务器上的路径指向目标 virtualenv 中站点包的实际位置)添加到我的 WSGI 文件中:

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
[Sun Jul 17 11:07:11 2011] [error] [client 94.170.105.142]     __import__(name)
[Sun Jul 17 11:07:11 2011] [error] [client 94.170.105.142] TemplateSyntaxError: Caught ImportError while rendering: No module named tagging

所以我猜 VirtualEnv 没有被加载。有人知道如何告诉 Apache/WSGI 使用正确的 virtualenv 吗？

更新

我已经按照 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 位于 root 中并且 apache 没有权限？我将该文件夹更改为 root:www-data 但它还没有解决问题。有什么建议吗？

Answer 1

在我的 app.wsgi 文件中，我有类似的内容。您需要将其更改为虚拟环境所在的位置，在本示例中，我的环境位于/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))
