[Qgis-user] PyQGIS from non-bundled Python install?

[Andrew Hughes]

Thanks Ujaval,

I was just about to respond as I found this:
https://docs.qgis.org/3.4/en/docs/pyqgis_developer_cookbook/intro.html#running-custom-applications

Your method looks completely different to that documented above. As I've
already started with the above method, I will continue unless I exhaust
that as an option.

I managed to get a docker image running (debian)  with qgis installed,
however these values I am using are no doubt wrong.
ENV PYTHONPATH=/usr/share/qgis/python
ENV LD_LIBRARY_PATH=/usr/lib/qgis

Could anyone suggest how I might find the correct values? At this stage,
python is not finding the packages "qgis.core.Qgis" == module not found

Thanks in advance,
Andrew
