Django - python3.4 virtualenv - apache

Question

我有一个 Django 应用程序，我一直在使用 manage.py runserver 进行调试。

我现在正尝试使用 apache/mod_wsgi 来提供它。

当我尝试打开主页时收到 500 错误。日志文件在 functools.py 中显示语法错误。

mod_wsgi (pid=28016): Target WSGI script '/home/username/projects/django/testing/testing/wsgi.py' cannot be loaded as Python module.
mod_wsgi (pid=28016): Exception occurred processing WSGI script '/home/username/projects/django/testing/testing/wsgi.py'.
Traceback (most recent call last):
File "/home/username/projects/django/testing/testing/wsgi.py", line 12, in <module>
  from django.core.wsgi import get_wsgi_application
File "/home/username/.virtualenvs/testing/lib/python3.4/site-packages/django/__init__.py", line 1, in <module>
  from django.utils.version import get_version

  cls_or_self, *rest = args
               ^
SyntaxError: invalid syntax

据我所知，这是有效的 python3.4 语法。所以我不完全确定我是否正确配置了 WSGI 以使用我的 virtualenv。

#testing.conf
<VirtualHost *:80>
    WSGIDaemonProcess django.testing.username.vni user=username group=username python-path=/home/username/.virtualenvs/testing/lib/python3.4/site-packages:/home/username/.virtualenvs/testing/lib/python3.4:/home/username/.virtualenvs/testing
    WSGIProcessGroup django.testing.username.vni

    WSGIScriptAlias / /home/username/projects/django/testing/testing/wsgi.py

    ServerAdmin username@webserver.com
    ServerName django.testing
    ServerAlias www.django.testing

    Alias /static/ /home/username/projects/django/testing/static/

    <Directory />
        AllowOverride None
        Options -Indexes
    </Directory>

    <Directory /home/username/projects/django/testing/testing>
        <Files wsgi.py>
            Require all granted
        </Files>
    </Directory>

    ErrorLog /var/log/apache2/django.testing.log
    LogLevel warn

</VirtualHost>

我想我上面的 python-path 可能有问题。

#wsgi.py
import os

from django.core.wsgi import get_wsgi_application

import sys
sys.path.append(os.path.dirname(os.path.abspath(__file__)) + "/..")
sys.path.append(os.path.dirname(os.path.abspath(__file__)))

#os.environ.setdefault("DJANGO_SETTINGS_MODULE", "testing.settings")
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "settings")

application = get_wsgi_application()

我不确定我是否正确处理了 sys.path.append() 或 DJANGO_SETTINGS_MODULE。他们就是为了解决我遇到的其他一些错误。

正如 Daniel Roseman 所建议的，问题是我为 python3.4 安装了错误的 mod_wsgi 版本。我删除了 libapache2-mod-wsgi 并安装了 libapache2-mod-wsgi-py3。
