Raspberry Pi render error

Hi, I’m using requests_html on my Raspberry Pi to do some easy web querying. However, calling html.render() results in the following error:

[W:pyppeteer.chromium_downloader] start chromium download.
Download may take a few minutes.

It seems like the downloaded chromium is not an arm executable. Has anyone ideas on how to fix this?

Also I want to add: the issue seems to be from pyppeteer installing the wrong architecture of chrome. Pi uses arm variants but the chrome architecture is x84-64.

Yeah that seems to be the problem according to the things I researched too.

How is the performance with selenium on your Pi?

It’s ok. I’m looking for JS generated text which works absolutely fine on a Pi 2. It may take some time for chromium to start but everything else works. Don’t know how good the objective performance is or something, but it just works.

Thanks, will give it a try! It’d work for our cases where we have the flexibility to change or write the scripts, but I’d imagine those who are porting existing scripts over might still prefer a solution within the library. Hope this gets looked into in the future.
