Django + Apache + mod_wsgi：导入错误

时间：2013-09-22 18:10:21

标签： python django apache wsgi importerror

我见过其他人在StackOverflow上发帖（主要是针对Django 1.4），但这些都没有为我提供成功的解决方案。我收到以下错误：

ImportError: Could not import settings 'myproject.settings' (Is it on sys.path?): No module named myproject.settings

Windows 8，Apache-2.2，Django-1.5.4，Python-2.7

答案 0 :(得分：3)

首先，我发现您的应用程序不在您的项目中，以及您的django.py，这很奇怪。 你的树应该是这样的：

── myproject/
 │   ├── django.wsgi
 │   ├── manage.py
 │   ├── myproject/
 │   │   ├── __init__.py
 │   │   ├── settings.py
 │   │   ├── urls.py 
 │   │   └── wsgi.py
 │   ├── myapp/
 │   │   ├── models.py
 ....

所以是的，我认为这是一个路径问题。

试试mod.wsgi：

import os
import sys

path = 'C:/your/path/myproject'
if path not in sys.path:
    sys.path.append(path)

os.environ['DJANGO_SETTINGS_MODULE'] = 'myproject.settings'

import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()

答案 1 :(得分：2)

您还没有通过更新sys.path告诉mod_wsgi您的包的位置。请参阅Django站点上mod_wsgi文档中的WSGIPythonPath设置。
