[Question] How to implement the micropip

[lawchin]

Question

You can use Micropip API directly in your Flet app:

https://flet.dev/docs/guides/python/publishing-static-website/

I dont know what I did wrong. and I dont know if I need or when to use pyodide & micropip.

Code sample

if sys.platform == "emscripten":
    import micropip
    await micropip.install("regex")

### Error message

```bash
await micropip.install("regex")
    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
SyntaxError: 'await' outside function

------------------------------------------------------

• I have searched for answers to my question both in the issues and in previous discussions.

Faced this same issue with a project some day. Forgot the package I was trying to import though.

Please @FeodorFitsner, make it clear.

OK, as micropip.install is async method by its nature you need to call it from async method. Therefore, Flet app must be async: https://flet.dev/docs/guides/python/async-apps

For example:

import flet as ft

async def main(page: ft.Page):

    if sys.platform == "emscripten":
        import micropip
        await micropip.install("regex")

    await page.add_async(ft.Text("Hello, async world!"))

ft.app(main)

ok thank you very much.. I hope it works this time

Alternatively, add regex to requirements.txt on a separate line.
