CodePudding user response：

Your declaration for <py-env> is incorrect. It should look like this:

<py-env>
  elasticsearch
</py-env>

Import elasticsarch like this:

<py-script>
 from elasticsearch import Elasticsearch
 ...

However, Elastic Search is not a supported package. It relies upon the Python Requests and ssl packages, which are supported by browsers. The Requests package uses the operating system TCP Socket API. That API is not available in the browser. This is not a PyScript limitation, it is a security restriction in the browser for all applications.

The only solution is to modify Elastic Search to use browser-supported APIs such as the Fetch API.
