不能使用Django和MongoDB

我得到django-nonrel，djangotoolbox並從GitHub mongodbengine和setting.py運行執行syncdb是如下：不能使用Django和MongoDB

DATABASES = { 
    'default': { 
     'ENGINE': 'django_mongodb_engine', # Add 'postgresql_psycopg2', 'postgresql', 'mysql', 'sqlite3' or 'oracle'. 
     'NAME': 'admin',      # Or path to database file if using sqlite3. 
     'USER': '',      # Not used with sqlite3. 
     'PASSWORD': '',     # Not used with sqlite3. 
     'HOST': '',      # Set to empty string for localhost. Not used with sqlite3. 
     'PORT': '',      # Set to empty string for default. Not used with sqlite3. 
    } 
} 

MIDDLEWARE_CLASSES = (
    'django.middleware.common.CommonMiddleware', 
    'django.contrib.sessions.middleware.SessionMiddleware', 
) 

ROOT_URLCONF = 'ptl.urls' 

TEMPLATE_DIRS = ('/Users/bxshi/PycharmProjects/ptl/templates',) 

INSTALLED_APPS = (
    'django.contrib.contenttypes', 
    'django.contrib.sessions', 
)

除了settings.py，我沒有任何其他.py文件在我的項目。

我得到的錯誤是：

BaoxuShis-MacBook:ptl bxshi$ python manage.py syncdb

我覺得與這個錯誤有關mongodbengine，在BBS上談論一個線程的東西，但它說，這已經是固定的。

你有Django的nonrel的普通安裝官方的安裝說明或您使用的例如buildout或virtualenv？從traceback看來，django正在從'/ Library/...'中使用，而djangotoolbox和django-mongodb-engine正在從'build/...'中使用。 – jhonkola

我剛剛從github獲得這些源代碼（Django Djangotoolbox等），然後使用'sudo python setup.py install'來安裝它。沒有使用'virutalenv'。事情是'Django1.4'安裝到我安裝'python'的路徑中，其他人安裝到'/ build/...' – bxshi

如果你使用了github的Django1.4倉庫，這可能不起作用。克隆django-nonrel回購。有關這方面的進一步討論，請參閱https://groups.google.com/d/topic/django-non-relational/Hj6hmX_2KIA/discussion。 – jhonkola

只需使用上https://django-mongodb-engine.readthedocs.org/en/latest/topics/setup.html

官方指南的django-nonrel已過期。這可能會導致一些關於插入元組的問題。所以我在github上找到了新的。我會嘗試使用virtualenv看看我能否解決它。 – bxshi

仍然有這個問題。也許我會嘗試使用Linux作爲我的開發服務器。 – bxshi

他們不過時。如果按照我所鏈接的說明進行操作，它應該會很好地工作。 –
