使用 django_elasticsearch_dsl 使用 django-python 建立索引的问题

Question

我正在使用 django-python 开发一个项目。它安装了“oaisearch”以从不同的网站检索元数据，并安装了“django_elasticsearch_dsl”以对它们进行索引。已验证 "oaisearch" 运行没有问题。当“python3 manage.py search_index --create -f”为运行开始索引时出现问题。具有您要索引的配置的文件“documents.py”如下。

from elasticsearch_dsl import analyzer

from django_elasticsearch_dsl import DocType, Index

from oaisearch.models import Digital_Resources

digital_resources = Index('digital_resources')

digital_resources.settings(
    number_of_shards=1,
    number_of_replicas=0
)

html_strip = analyzer(
    'html_strip',
    tokenizer="standard",
    filter=["standard", "lowercase", "stop", "snowball"],
    char_filter=["html_strip"]
)

@digital_resources.doc_type

class Resources(DocType):
    class Meta:
        model = Digital_Resources
        fields = [
            #'oai_server',
            'creator',
            'title',
            'subject',
            'description',
            'identifier',
        ]

执行上述命令后的控制台失败信息如下

您使用的是哪个版本的 elasticsearch 运行？看起来你是运行 elasticsearch 7.x，你的 django_elasticsearch_dsl 版本还不支持它。尝试寻找较新的版本或使用 elasticsearch 6.x.
