Failed to use pyodide-kernel out of Jupyterlite

[MRYingLEE]

In a Javascript environment,

import pyodide from 'https://cdn.jsdelivr.net/npm/pyodide@0.27.2/+esm'

works.

In order to have additional features, I tried to use pyodide-kernel but failed.

Both

import jupyterlitepyodideKernel from 'https://cdn.jsdelivr.net/npm/@jupyterlite/pyodide-kernel@0.5.2/+esm'

and

const jupyterlitepyodideKernel = await import('https://cdn.jsdelivr.net/npm/@jupyterlite/pyodide-kernel@0.5.2/+esm');

caused

Error: Failed to bundle using Rollup v2.79.2: failed to resolve an internal import. If you believe this to be an issue with jsDelivr, and not with the package itself, please open an issue at https://github.com/jsdelivr/jsdelivr
    at https://cdn.jsdelivr.net/npm/@jupyterlite/pyodide-kernel@0.5.2/+esm:6:8

await import("https://cdn.jsdelivr.net/npm/@jupyterlite/pyodide-kernel@0.5.2/lib/index.min.js")

caused

SyntaxError: [2:95]: Unterminated template literal

Just wonder whether it is possible to use pyodide-kernel without Jupyterlite.

Please clarify.
Thanks,
