• Install Conda
• Create conda environment; e.g: $ conda create -n pyloess python=3.6 gfortran_osx-64 gcc numpy
• Activate environment: $ source activate pyloess
• Clean: $ rm -rf build/*
• Install: $ python setup.py install

NOTE: On recent version of MacOS you may have to manually install the C include files as some Mojave patches apparently delete them and xcode-select --install no longer re-installs them. I found this helpful.

• Sanity check:

$ python
>>> from pyloess import stl
