The versions of es related libraries are as follows:
django-elasticsearch-dsl==7.2.0
elasticsearch==7.12.0
elasticsearch-dsl==7.2.0
I accidentally started an es6 version of homebrew on my mac before, but after switching to the es version for a long time, I still got an error. Stop the es of homebrew and manually start the es7 version and it will be normal.
