pyqgis - Getting QGIS python modules to work from PyScripter in Windows 10?

Been trying lots of "solutions" from net research but nothing seems to work.

I have the current versions of QGIS from OSGEO and PyScripter 2.5

Based on one of the solutions I tried...

import sys
sys.path.extend([r"C:\OSGeo4W64\apps\qgis\python",r"C:\OSGeo4W64\apps\qgis\bin"])
sys.path.reverse()
import qgis.core

gives me

Message File Name Line Position Traceback
4
C:\OSGeo4W64\apps\qgis\python\qgis__init__.py 26 ImportError: No module named sip

import processing

gives me

ImportError: No module named processing

and path is

PATH=C:\ProgramData\Oracle\Java\javapath;C:\Python27\;C:\Python27\Scripts;C:\Program Files (x86)\Intel\iCLS Client\;C:\Program Files\Intel\iCLS Client\;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;C:\Program Files\Intel\Intel(R) Management Engine Components\DAL;C:\Program Files\Intel\Intel(R) Management Engine Components\IPT;C:\Program Files (x86)\Intel\Intel(R) Management Engine Components\DAL;C:\Program Files (x86)\Intel\Intel(R) Management Engine Components\IPT;C:\Program Files\Intel\WiFi\bin\;C:\Program Files\Common Files\Intel\WirelessCommon\;C:\Program Files (x86)\NVIDIA Corporation\PhysX\Common;C:\Program Files (x86)\Windows Live\Shared;C:\Program Files (x86)\Skype\Phone\;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\WINDOWS\System32\WindowsPowerShell\v1.0\;C:\Program Files (x86)\QuickTime\QTSystem\;C:\Program Files\Intel\WiFi\bin\;C:\Program Files\Common Files\Intel\WirelessCommon\; C:\OSGeo4W64\bin 

pythonpath includes

C:\OSGeo4W64\apps\qgis\bin
C:\OSGeo4W64\apps\qgis\python

and

Problem with import qgis.core when writing a stand-alone PyQGIS script

after running the .bat in above I get "ImportError: no module name qgis.core" in python within osgeo shell as well.

Answer

Your PYTHONHOME should be:

C:\OSGeo4W64\apps\Python27

Your PATH should include (in the beggining):

C:\OSGeo4W64\bin; C:\OSGeo4W64\apps\qgis\bin 

PYTHONPATH should have:

C:\OSGeo4W64\apps\qgis\python
C:\OSGeo4W64\apps\qgis\python\plugins
C:\OSGeo4W64\bin\python27.zip

C:\OSGeo4W64\apps\Python27\DLLs
C:\OSGeo4W64\apps\Python27
C:\OSGeo4W64\apps\Python27\lib
C:\OSGeo4W64\apps\Python27\lib\site-packages

In code you have to:

import sys
from qgis.core import QgsApplication

QgsApplication.setPrefixPath('C:\OSGeo4W64\apps\qgis', True)

qgs = QgsApplication(sys.argv, False)
qgs.initQgis()

If you don't have sip in your Python installation you should install it.

EDIT

Provided you are running the correct python version for pyqgis you can setup everything in python code:

import sys, os

os.environ['PATH'] = 'C:\\OSGeo4W64\\apps\\qgis\\bin;C:\\OSGeo4W64\\bin;' + os.environ['PATH']
sys.path.extend(['C:\\OSGeo4W64\\apps\\qgis\\python', 'C:\\OSGeo4W64\\apps\\qgis\\python\\plugins', 'C:\\OSGeo4W64\\bin\\python27.zip', 'C:\\OSGeo4W64\\apps\\Python27\\DLLs', 'C:\\OSGeo4W64\\apps\\Python27', 'C:\\OSGeo4W64\\apps\\Python27\\lib', 'C:\\OSGeo4W64\\apps\\Python27\\lib\\site-packages'])
