I am trying to deploy my Python app on Heroku, but have been unsuccessful. It seems that a problem is occurring with the PyICU package, which I'm unsure how to correct. I've confirmed that this is the only issue with my deployment; when I remove PyICU from my requirements file, everything works. But of course my site can't work without it.
Can anyone please guide me in how to correctly install this package on Heroku? I've tried various methods, including downloading the .whl file and then adding that to my requirements file, but then I get another error:
ERROR: PyICU-2.7.3-cp38-cp38m-win_amd64.whl is not a supported wheel on this platform. I don't understand why - it's the correct Python and os version.
Here are the relevant excerpts from the build log:
-----> Building on the Heroku-20 stack
-----> Using buildpack: heroku/python
-----> Python app detected

I would be very grateful if someone can recommend a fix, thanks. I know that PyICU is not the easiest to install even locally, but how do I go about telling Heroku how to do it?
Edit: I tried adding a custom buildpack for ICU: https://github.com/generalassembly/heroku-icu-buildpack
It seems to run a bit differently then, but still get errors with regard to locale and also the following:
gzip: stdin: not in gzip format
tar: Child returned status 1

I haven't tried this myself, but it may be possible to use
heroku-buildpack-aptto install PyICU using their Debian installation method.Otherwise, your wheel needs to be the same version as the server's operating system, not your development machine's OS. You can try building the wheel inside the Heroku dyno using a technique in this StackOverflow answer.
I don't have a repo to test these methods, so I'm not sure how well they'll work. I will be happy to update this answer if you try them out.
