在 windows 上使用 django mongodb 引擎在 django 中设置 MongoDB 时出错

Question

我遵循的步骤：

1. 'pip install git+htp://github.com/django-nonrel/django@nonrel-1.5'

它不起作用，所以我从站点“htp://github.com/django-nonrel/django”下载了 zip，并将解压后的文件夹粘贴到“c:\users\hp\appdata\local\temp”中\pip-m0d0y9bv-build”。

1. 'pip install git+htp://github.com/django-nonrel/djangotoolbox'
2. 'pip install git+htp://github.com/django-nonrel/mongodb-engine'

注意

*** 因为我的声誉低于 10，所以我使用了 'htp' 而不是 'https'。

4. 将我的 settings.py 文件配置如下：-

.

import os       

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))         

SECRET_KEY = '4j*aieq$cn&sewl0s2#&m00+^oe%qg9p=@mlva96_r48nv-pkl'

DEBUG = True

ALLOWED_HOSTS = []


INSTALLED_APPS = (
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'myapp',
    'djangotoolbox',
)

MIDDLEWARE_CLASSES = (
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.auth.middleware.SessionAuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
    'django.middleware.security.SecurityMiddleware',
)

ROOT_URLCONF = 'myproject.urls'

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',
            ],
        },
    },
]

WSGI_APPLICATION = 'myproject.wsgi.application'



DATABASES = {
    'default': {
        'ENGINE': 'django_mongodb_engine',
        'NAME': 'test',
        'USER': '',
        'PASSWORD': '',
        'HOST': 'localhost',
        'PORT': 27017,


    }
}

SESSION_ENGINE = 'mongoengine.django.sessions'
SESSION_SERIALIZER = 'mongoengine.django.sessions.BSONSerializer'


LANGUAGE_CODE = 'en-us'

TIME_ZONE = 'UTC'

USE_I18N = True

USE_L10N = True

USE_TZ = True

STATIC_URL = '/static/'

5. 使用命令“python manage.py runserver”开始运行服务器时出现以下错误

。

c:\Python34\myproject>python manage.py runserver

我在这里缺少什么？我已按照 django - mongoengine 文档中的步骤进行操作。但是，我无法弄清楚这个问题。请帮我解决这个问题。

Answer 1

Django-mongodb-engine 似乎与 Python 3 不兼容。无论如何，django-nonrel 本身是基于 Django 1.5 的，它绝对不兼容 Python 3。
