我一直抛出一个异常，说没有安装模块。任何帮助将非常感激。

我环顾四周，有人建议可以通过扩展 sys 路径以包含应用程序目录来解决此错误。我很确定 WSGI 文件中的 sys.path 指令会处理一些事情：

import os, sys
sys.path.append('/home/osqa')
sys.path.append('/home/osqa/trunk')
os.environ['DJANGO_SETTINGS_MODULE'] = 'trunk.settings'
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()

错误输出如下所示：

[info] mod_wsgi (pid=15737): Attach interpreter ''.
[info] mod_wsgi (pid=15737): Create interpreter 'trunk|'.
[info] [client 172.31.0.6] mod_wsgi (pid=15737, process='OSQA', application='trunk|'):

forum.middleware.extended_user: "No module named markdown"

Apache Config 如下所示：

WSGISocketPrefix run/wsgi
<VirtualHost *:80>
ServerAdmin xxx@xxx.com   
DocumentRoot /home/osqa/trunk
ServerName trunk   
CustomLog logs/osqa.access.log common   
ErrorLog logs/osqa.error.log
WSGIScriptAlias / /home/osqa/trunk/apache/django.wsgi
<Directory> /home/osqa/trunk/apache>
            Order deny,allow
            Allow from all
</Directory>

WSGIDaemonProcess OSQA
WSGIProcessGroup OSQA
Alias /m/ /home/osqa/trunk/forum/skins/     
<Directory /home/osqa/trunk/forum/skins>
            Order deny,allow
            Allow from all
</Directory>

    <Directory /home/osqa/trunk/forum/upfiles>

    </Directory></VirtualHost>

forum.middleware.extended_user 看起来像这样： from django.contrib.auth.middleware import AuthenticationMiddleware from django.contrib.auth import logoutfrom forum.models.user import AnonymousUser from forum.views.auth import forward_suspended_userimport logging

class ExtendedUser(AuthenticationMiddleware):
def process_request(self, request):
    super(ExtendedUser, self).process_request(request)
    if request.user.is_authenticated():           
     try:
            request.user = request.user.user
            if request.user.is_suspended():       
                user = request.user
                logout(request)
                return forward_suspended_user(request, user)
                return None            
                except Exception, e:               
                    import traceback
                    logging.error("Unable to convert auth_user %s to forum_user: \n%s" % (                           request.user.id, traceback.format_exc()
                    ))
    request.user = AnonymousUser()
    return None

您能否发布这个引发异常的中间件，以便我们可以准确地看到它试图导入的内容？

听起来它正在导入降价，而降价不在你的路上。通常，它会安装在您的site-packages目录中，而不是安装在您的项目中。

尝试pip install markdown

更新：你说它肯定是安装的。降价安装在哪里？
