Python Django+；干草堆+；生成xml时出现Solr错误

我试图运行“python manage.py

build\u solr\u schema

，但遇到了不允许我从数据库生成xml的错误。我的solr服务器已启动并运行良好，我可以看到solr服务器的初始页面。以下是完整的错误代码

错误：

Save the following output to 'schema.xml' and place it in your Solr configuratio
n directory.

这里得到了类似的结果。你找到答案了吗？这个最简单的解决方案对我来说适用于whoosh、solr和elasticsearch。只需按原样实现并更改solr的设置。你可能需要安装solr server。

from django.core.paginator import Paginator
# Create your views here.
from .models import Product
from django.views.generic.list import ListView
from django.views.generic.detail import DetailView

class ProductListView(ListView):
    model = Product
    paginate_by = 20

    def get_context_data(self, *args, **kwargs):
        context = super(ProductListView, self).get_context_data(*args, **kwargs)
        return context

    def get_queryset(self, *args, **kwargs):
        context = super(ProductListView, self).get_queryset(*args, **kwargs)

        return context

class ProductDetailView(DetailView):
    model = Product
