Unable to install Enchant C library

My heroku app makes use of the enchant library. When I go to deploy, I get this log from heroku logs:

So doing a little research I find that the enchant library makes use of the underlying Enchant C library which is an apt-based dependency. So the proper way to handle this problem in heroku is to use heroku-buildpack-apt. I use the Ubuntu Packages Search to find the proper name for the Enchant C library. In particular, I try "enchant-2", "libenchant-2-2", "python3-enchant" by adding them to the Aptfile. When I push the changes to heroku, I get logs assuring me that it is using the heroku-community/apt buildpack and is installing the enchant library that I specified in the Aptfile. However, the same above error always occurs.

It seems that this issue has popped up a couple times on the internet but has gone unresolved with most people just opting to not use the enchant library entirely which I may concede to doing as well.

Anyone know how to solve this problem?
