[Qgis-user] How to get Spyder IDE working with QGIS

[John Walker]

Hi, would anyone know how to configure Spyder to work with the QGIS
library? I am finding the python editor in QGIS difficult to work with
because it has no debugger and I cannot run highlighted code. I have tried
a few things:

1. created a new conda environment and installed QGIS via conda using: conda
install -c conda-forge qgis. However I get errors when trying to import
qgis.core

2. installed Spyder within OSGeo4W QGIS python instance i.e.

py3-env
python -m pip install spyder

But this gives errors in the IPython console i.e.

SyntaxError: invalid syntaxFile
"C:\OSGEO4~1\apps\Python36\lib\site.py", line 177
file=sys.stderr)

Thanks for any help.

You could try the bat in this repository:

https://github.com/frankbroniewski/visual-studio-code-qgis

simply change in the last line of the bat from "code.exe" (this is the
Visual Studio Code IDE) with the exe of your IDE.

Hi John,

If you figure this one out, can you poste the solution? I would like to do the same thing.

Thanks
Nicolas

Thanks Luca,

That script is actually similar to the script contained
in C:\OSGeo4W64\bin\python-qgis.bat which I have been testing. When I open
a OSGeo4W Shell and execute that script and type 'import qgis.core' into
the python console, it has no issues. When I exit the python console
(pressing ctrl-z) and start spyder3 (which I pip installed previously) it
have no issues with 'import qgis', but it complains when I 'import
qgis.core', giving me the error:

ImportError: DLL load failed: The specified procedure could not be found.

I read on
https://nathanw.net/2014/05/10/setting-up-pycharm-for-pyqgis-and-qt/ that
when you want to get PyCharm working with qgis, you need to change the
python interpreter in PyCharm. So I changed the python interpreter in
spyder to C:\OSGeo4W64\bin\python3.exe, and restarted the kernel. I now get
the following error in spyder's python console:

An error ocurred while starting the kernel
File "C:\OSGeo4W64\apps\Python36\lib\site.py", line 177
file=sys.stderr)

If however I execute PyCharm after running the
C:\OSGeo4W64\bin\python-qgis.bat script, and setting the PyCharm python
interpreter to C:\OSGeo4W64\bin\python3.exe, it works flawlessly. I guess
at this stage I will use PyCharm and abandon my efforts with getting things
working in Spyder, which will be a pain for me as I really love spyder.
Thanks again for your help.

Cheers.

Actually, I take that back. It doesn't seem to work in PyCharm after
further testing. I get the following error:

ImportError: DLL load failed: The specified procedure could not be found.

Not sure what to do now.
