Question

我无法解决在django 1.6应用程序下创建新的sqlite3数据库的问题。当我在做python manage.py syncdb时，它允许我创建一些表格，如：

Creating table django_admin_log                                                 
Creating table auth_permission                                                  
Creating table auth_group_permissions                                           
Creating table auth_group                                                       
Creating table auth_user_groups                                                 
Creating table auth_user_user_permissions                                       
Creating table auth_user                                                        
Creating table django_content_type                                              
Creating table django_session

...但经过一些追溯后，它以错误结束：

我的设置包括：

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': 'database.db',
    }                                                  
}

我不知道如何解决这个问题。有人可以帮帮我吗？

Answer 1

我假设你正在使用Alwaysdata的托管服务，因为我用Google搜索了这个问题，这是关于Alwaysdata论坛的同一个问题：Django sqlite3 - an error when manage.py syncdb。

我解决此问题的方法是在我的Alwaysdata管理页面中切换到较低版本的Django（例如1.5.5）。然后可以成功创建db文件。

我仍然没有理由发生这种情况。
