    我知道这个问题很老，但我想分享一下如何解决这个问题 .

    • 如果您在本地使用elasticsearch

    您必须做的第一件事是在您的机器上运行elasticsearch .

    Error: Request error, retrying -- connect ECONNREFUSED 127.0.0.1:9200

    因为上面的消息表明您没有在本地运行elasticsearch .

    所以，访问link并按照行为进行操作 .

    • Docker环境

    这里变得更加棘手 .

    首先，按照说明here .

    如果您使用的是node.js elasticsearch客户端，则必须将 elasticsearch host 指定为 172.24.0.1 .

    如果在 docker-compose.yml 中使用 container_name 或_16602010_，则无效 .
