uj5u.com熱心網友回復：
您的宣告<py-env>不正確。它應該如下所示：
<py-env>
elasticsearch
</py-env>
像這樣匯入elasticsarch：
<py-script>
from elasticsearch import Elasticsearch
...
但是，Elastic Search 不是受支持的軟體包。它依賴于瀏覽器支持的 PythonRequests和包。ssl該Requests軟體包使用作業系統 TCP Socket API。該 API 在瀏覽器中不可用。這不是 PyScript 限制，它是瀏覽器中所有應用程式的安全限制。
唯一的解決方案是修改 Elastic Search 以使用瀏覽器支持的 API，例如Fetch API。
