Question

我在Debian系统上用apache2 + mod_wsgi建立一个django服务器（1.4，python 2.7）。从django方面来说，一切都很完美，如果我运行manage.py runserver，开发服务器会正确显示网站，但是，当我尝试设置我的apache服务器来运行WSGI时，它无法显示ValueError。

这是 mysite.wsgi

ALLDIRS = ['/usr/local/lib/python2.7/site-packages']
# the above directory depends on the location of your python installation.
# if using virtualenv, it will need to match your projects locale.
import os
import sys
import site

os.environ['DJANGO_SETTINGS_MODULE'] = 'ggDatabase.settings'
prev_sys_path = list(sys.path)
sys.path.append("/usr/local/lib/python2.7")
path = "/home/acad/statsdb/src"
if path not in sys.path:
        sys.path.append(path)
        sys.path.append("/home/acad/statsdb/src/ggDatabase")
for directory in ALLDIRS:
        site.addsitedir(directory)
        new_sys_path = []
        for item in list(sys.path):
            if item not in prev_sys_path:
                new_sys_path.append(item)
                sys.path.remove(item)
                sys.path[:0] = new_sys_path

# change this depending on your project.

site.addsitedir("/home/acad/statsdb/src/ggDatabase/")


os.environ['PYTHON_EGG_CACHE'] = '/home/acad/.python-eggs'
os.environ['SETTINGS_MODULE'] = 'settings'
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()

这是 apache VirtualHost配置：

<VirtualHost 127.0.0.1:8000>
    ServerName mysite.com
    ServerAlias www.mysite.com
    <Directory /home/acad/statsdb/src/ggDatabase>
        Order deny,allow
        Allow from all
    </Directory>

    LogLevel warn
    CustomLog /var/log/apache2/mysite.com.access.log combined
    ErrorLog /var/log/apache2/mysite.com.error.log

    WSGIDaemonProcess mysite.com user=acad group=acad threads=25 python-path=/usr/local/lib/python2.7
    WSGIProcessGroup mysite.com
    WSGIScriptAlias / /home/acad/statsdb/src/ggDatabase/apache/mysite.wsgi

</VirtualHost>

这是我在测试服务器上的确切配置，它在那里工作，但新服务器在尝试运行wsgi脚本时遇到问题：

错误是如此通用，以至于我真的不知道会出现什么问题。有什么想法吗？

提前致谢！

解决了它。如果有人有类似的错误，请确保打印sys.version，你可能会发现（正如我所做的）wsgi是在另一个已安装的python版本下配置的。

如果是这种情况，请使用--with-python选项重新安装mod_wsgi。
