In testing "pip install ." and "pip uninstall" ran into this issue about the numba compiled cache not being deleted by pip when uninstalling.

Discussion in Numba community: numba/numba#9312

Perhaps adjust cache directory using NUMBA_CACHE_DIR environment variable? https://numba.readthedocs.io/en/stable/reference/envvars.html#envvar-NUMBA_CACHE_DIR
