The note about Python is that, unfortunately, the python distribution we use ATM is not compatible with MacOS 10.11 and 10.12. One way how to fix it is probably use Python official distribution and not Homebrew distribution in the process of creation of our package.

Ah ok cool thanks for the clarification. I can confirm that the package I downloaded last night picks up the python interpreter inside the bundle nicely:

import sys
for p in sys.path:
	print(p)
/Users/timlinux/Library/Application Support/QGIS/QGIS3/profiles/default/python/plugins/karika
/Applications/QGIS3.4.2.app/Contents/MacOS/../Resources/python

/Applications/QGIS3.4.2.app/Contents/Resources/python
/Applications/QGIS3.4.2.app/Contents/Frameworks/Python.framework/Versions/Current/lib/python3.7/site-packages


What is the recommended way to install additional deps (e.g. via pip) into the bundled python environment? If we try to just directly  use the python interpreter (see below) it does not have the correct python path:

Maybe we need to bundle in pip and a tool from within QGIS to call pip (some examples were given on this mailing list in the past) from within QGIS so that the python interpreter has the correct context….this would probably be useful for windows users too?
