So QGIS, at least on a Mac, does seem to have it's own version of Python installed. And there is not clear way, again on a Mac at least, to pip install to the QGIS Python such that a plugin will be able to see a package. Now, this said, on my Linux machine,
installing my Whitebox Workflows plugin did not run into an error at all and so I'm left wondering if this is perhaps, as Greg suggested, a particular binary distribution issue related to QGIS on MacOS. Could be.</div>

The OS4Geo binary distribution contains a Python39 directory which is a full python installation including python.exe, a Lib directory which in turn contains a site-packages directory. As least in my case, this is installed system-wide, not per-user<br>
