Hello @JLeon and welcome to the forums! It was great to see you in person a few weeks back.
You’re right that the InVEST API docs are a little out of date in this respect. I’ll update the docs. The easiest way to install natcap.invest using conda or mamba is:
mamba install natcap.invest
That will grab everything needed and will work on Mac (both intel and M1/M2 chips) and Windows (and probably linux, too).
Note that since we have deprecated the Qt interface, there is no UI that comes with the conda installation. The above will install everything you need to be able to write programs that call InVEST models.
