关键代码：

1
outputElement.innerText += '\n正在安装 lcapy...';
2
await pyodide.runPythonAsync(`
3
    import micropip
4
    await micropip.install('lcapy',deps=False)
5
`);

当频繁出现

ValueError: Can’t find a pure Python 3 wheel for ‘importlib’. See: https://pyodide.org/en/stable/usage/faq.html#why-can-t-micropip-find-a-pure-python-wheel-for-a-package You can use await micropip.install(…, keep_going=True) to get a list of all packages with missing wheels.

这类下载不到官方库的抽象问题时，并不要去keep_going=True，而是应该自己加载好所有的依赖await pyodide.loadPackage(["numpy", "scipy", "sympy", "matplotlib", "networkx"])，忽略原来提供的包依赖deps=False。
