python - Django、WSGI 和 Apache 的语法错误

Question

我在尝试使用 mod_wsgi 在 Apache 下运行 Django 站点时遇到奇怪的错误。我已经为此工作了几个小时，但毫无结果。

仅供引用:我也在使用 Mezzanine。

mysite 的 httpd.conf(服务器上还有其他)

# Redirects all HTTP traffic to HTTPS
<VirtualHost *:80>
    #ServerName test-mysite
    #ServerAlias test-mysite mysite.com mysite
    ServerName mysite.com

    DocumentRoot /opt/mysite

    RewriteEngine On

    WSGIScriptAlias / /opt/mysite/mysite/wsgi.py

</VirtualHost>

WSGISocketPrefix /var/run/wsgi

    <Directory /opt/mysite/mysite>
        Options +FollowSymLinks -Indexes

httpd -V 输出:

Python 2.6 不支持 set 语法 {....}

您可以use a version of Django that supports Python 2.6但请确保它也支持 Mezzanine或者将您的 Python 安装更新到 2.7
