Python django haystack运行时出错"/manage.py重建索引

我在运行时遇到以下类型错误：

python manage.py rebuild_index

我当前的设置是Solr 4.8.1、django haystack 2.1.0、django 1.6.2和Python 3.4.0

有人知道这是什么原因吗？以下是错误线程：

在我的案例中，django_id出现了问题。帮助我的是这个问题。我做了以下几件事：

• 将模式放在solr-x.y.z/example/solr/collection1/conf/schema.xml中

• 将版本字段（如下所述）添加到中的架构中

  <field name="django_id" type="string" indexed="true" stored="true" multiValued="false"/>
