我使用 Apache Solr 已经有一段时间了,直到最近才开始遇到一些严重的问题。我将它与 haystack 和 django 项目一起使用。当我这样做时,manage.py shell
我得到以下信息:
>>> from haystack.query import SearchQuerySet
>>> emps = SearchQuerySet().filter(django_ct='web.employer').filter(name__icontains='Mi')[:10]
Traceback (most recent call last):

我尝试重新安装 haystack、lxml、cssselect、pysolr,但我仍然收到这些错误。还有什么我可以尝试的吗?谢谢你的帮助!
