PyQGIS standalone script using QGIS 3.2

Question

I want to work with PyQGIS Python 3 using QGIS 3.2 standalone install. I created a simple batch file to work with PyQGIS but I have some errors.

Here's the batch file:

@echo off
SET OSGEO4W_ROOT=C:Program FilesQGIS 3.2

call "%OSGEO4W_ROOT%"bino4w_env
call "%OSGEO4W_ROOT%"appsgrassgrass-7.4.1etcenv.bat
@echo off
path %PATH%;%OSGEO4W_ROOT%appsqgisbin
path %PATH%;%OSGEO4W_ROOT%appsgrassgrass-7.4.1lib
path %PATH%;%OSGEO4W_ROOT%appsQt5bin
path %PATH%;%OSGEO4W_ROOT%appsPython36Scripts

set PYTHONPATH=%PYTHONPATH%;%OSGEO4W_ROOT%appsqgispython
set PYTHONHOME=%OSGEO4W_ROOT%appsPython36

SET PYCHARM="C:Program FilesJetBrainsPyCharm 2018.1.4binpycharm.exe
start "PyCharm aware of QGIS" /B %PYCHARM% %*

Error is:

File "C:PROGRA~1QGIS3~1.2appsPython36libsite.py", line 177
    file=sys.stderr)
        ^
SyntaxError: invalid syntax

The problem may be caused by incorrect PyCharm setup, check this answer: Why does QGIS 3.2 "native:extractvertices" algorithm not work properly in standalone script?

Jessie, I suspect there may be a problem with this line in your batch file:

SET OSGEO4W_ROOT=C:Program FilesQGIS 3.2

try setting it to your OSGeo4W64 root folder like below:

SET OSGEO4W_ROOT=C:OSGeo4W64
