python之找不到名为 os 的模块——Django、mod_wsgi、Apache 2.2

我正在尝试设置 apache、mod_wsgi 和 django。我在我的 apache 错误日志中收到一个内部服务器错误:

[Wed Jun 22 21:31:55 2011] [error] [client ::1] mod_wsgi (pid=2893): Target WSGI script '/django/internal/django-development.wsgi' cannot be loaded as Python module.

django-development.wsgi

#! /usr/bin/env python 
 
import sys, os 
 
path = '/django/internal' 
if path not in sys.path: 
    sys.path.append(path) 
 
os.environ['DJANGO_SETTINGS_MODULE'] = 'internal.settings' 
 
import django.core.handlers.wsgi 
application = django.core.handlers.wsgi.WSGIHandler() 

请让我知道是否有任何东西(例如配置文件)我可以发布以帮助您帮助我诊断此问题。

这很奇怪，考虑到我认为我将我的默认 python 版本设置为 2.5..，并使用 python2.5 作为参数运行 ./configure

$otool -L mod_wsgi.somod_wsgi.so: 
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 125.2.10) 
    /System/Library/Frameworks/Python.framework/Versions/2.6/Python (compatibility version 2.6.0, current version 2.6.1) 

和

LoadModule wsgi_module libexec/apache2/mod_wsgi.so 
WSGIScriptAlias / /django/internal/django-development.wsgi

啊，好像导入了错误的配置文件。我已经得到它现在给我以下输出。进度:

所以，我仍然想弄清楚如何让 mod_wsgi 运行 python 2.5 而不是 2.6——这就是我现在遇到的大问题。除此之外，它应该只是调整 apache 配置。

请您参考如下方法:

mod_wsgi 由于某种原因无法看到您的 Py2.5 库。我建议检查 WSGIPythonPath 的值并确保它指向类似/usr/lib/python2.5 的内容
