@Pedro:
Tried it today on Windows w OSGeo QGIS and failed right away. But in a
different way:
If I launch OSGeo QGIS and ask for the python executable's path
(sys.executabe), I get 'C:/OSGeo4W/bin/qgis-bin.exe'. which looks like
entry point is for QGIS. So subprocess calls that and a new QGIS window
opens.
Not feeling like tackling this and probably other cases.
So back to download+including those bins I reckon.
@Johannes:
Thank you. Yes realizing that now..
Cheers,
Aron

Trying to find a smart way to install Python dependencies for the
users that will not potentially not work or even break stuff is a very

Hey Aron,
I did explore that route, but I found out that it
would fail when the user did not have administrator rights (or even
if QGIS had not been ran as administrator on Windows). Did you find
it to be different?
Cheers,
Pedro

Thank you, I checked out your plugin - yes that seems also a good
way.
I already had the logic to detect, throw message, guide to
dialog, etc... implemented similar to yours.
But I wanted to let pip manage the actual package, so I went with
the subprocess+pip route. Here is a minimum working example:
import subprocess
import sys
try:
subprocess.check_call((sys.executable, '-m', 'pip', 'install',
'h3<=3.99'))
except subprocess.CalledProcessErroras e:
raise e# handle any errors here instead
I connected it to a button in a dialog. And catch stdout, stderr
and the exit code of the subprocess so I can show the user what
is happening.
Have not yet tried on other platforms than Linux. But
sys.executable is there to solve the ambiguity of python
executable path.
Best regards,
Aron
