python - Elasticsearch 5.2、Python 3 属性错误 : 'Elasticsearch' object has no attribute 'delete_by_query'

Question

iam 使用此代码从我的索引中删除文档:

from elasticsearch import Elasticsearch 
es= Elasticsearch()

index = 'test'
doc_type = 'trends' 

q = {
"query": {
    "match": {
        "Device": "12 Bel"
        # find the docs those schould be deleted
    }
 },    
}

result = es.delete_by_query(body=q, doc_type=doc_type, index=index)
print('Result is : ', result)

我收到此错误:

AttributeError: 'Elasticsearch' object has no attribute 'delete_by_query'

有人遇到过这个问题吗？有什么帮助吗？谢谢

我已经检查了 https://github.com/elastic/elasticsearch-py/blob/master/elasticsearch/client/init.py 上的代码Elasticsearch 类包含 delete_by_query 方法。所以这不应该发生。可能的原因是您从旧版本(<5.0)升级了elasticsearch-py，并且旧的python库文件没有被删除。尝试删除elasticsearch-py模块并重新安装，这应该可以解决。
