TypeError: index() got an unexpected keyword argument 'doc_type'
es 版本升级之后,doc_type没有这个参数了
尝试安装低版本的

Seems your elasticsearch python client version is higher than v5.6.
Remove the existing one with a doc_type compatible version e.g 5.5.3
Remove: pip uninstall elasticsearch and then Install pip install elasticsearch==5.5.3
N.B I'm suggesting to do that because elasticsearch doesn't support multiple doc types文章来源：https://www.toymoban.com/news/detail-419303.html
per index any more using doc_type文章来源地址https://www.toymoban.com/news/detail-419303.html
