Thanks for the report. This is caused by a distutils.cfg file provided by Homebrew. I've added more details to the end of this answer, and we'll fix this in the next version of Chaquopy.

Meanwhile, it looks like the bug was introduced in Chaquopy 9.0.0, so try editing your top-level build.gradle file to go back to the previous version, 8.0.1.

This issue is fixed in Chaquopy 9.1.0. To upgrade, edit your app's top-level build.gradle file and change the version number of com.chaquo.python:gradle.
