[QGIS-Developer] QGIS plugin depends on pypi package

[John Lindsay]

Agreed, when I 'print(sys.executable)' from within the QGIS Python Console (on my MacBook Pro), I see:


/Applications/QGIS.app/Contents/MacOS/QGIS


But from my system terminal, I see:


/Library/Frameworks/Python.framework/Versions/3.11/bin/python3

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.

Regards,

John

When you say "qgis seems to use its own version", I wonder if that is in
the context of particular binary distribution.  And if there really is a
full extra copy of libs, or if it's about a per-user site-packages
directory.

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
