Description

I download and install QGIS Standalone from: https://qgis.org/en/site/forusers/download.html

Using the standalone installer (both 3.4.5 and 3.6.0) the QGIS python console cannot find the PIL library that is installed (installed in folder = apps/python27/Lib/site-packages).
The impact is that this prevents several of the python dependent user plugins working properly with QGIS installed via the standalone installer. For example plugin Lecos will not load.
To reproduce: install QGIS using the standalone installer, then test whether PIL is installed and available by opening the QGIS python console (Menu -> Plugins -> Python console) and then type

import PIL
PIL.__version__

I don´t know python but the python libraries appear to be mis-specified (1.4 when should be 3.4). See end of traceback....

QGIS3 used python3 - the pil in python2 is used by GRASS. A pil for python3 is neither required nor included in the standalone - but the next one will also include python3-pillow.

Nope, QGIS3~1.4 is the short path for QGIS 3.4.
