您对
＆lt; py-env＆gt;的声明是不正确的。它应该看起来像这样：类似的导入弹性核管：
但是，弹性搜索不是受支持的软件包。它依赖于Python
请求和ssl软件包，这些软件包由浏览器支持。请求软件包使用操作系统TCP套接字API。该API在浏览器中不可用。这不是Pyscript限制，它是所有应用程序的浏览器的安全限制。唯一的解决方案是修改弹性搜索以使用浏览器支持的API，例如获取API 。
Your declaration for
<py-env>is incorrect. It should look like this:Import elasticsarch like this:
However, Elastic Search is not a supported package. It relies upon the Python
Requestsandsslpackages, which are supported by browsers. TheRequestspackage 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.
