Running Kivy1.11 (Py3.6 with SDL2) in VSCode - python-3.x

Question

I'm trying to debug my GUI in VSCode(1.39.1) using kivy1.11, python3.6.9 and Win10, but VSCode cannot compile.
I installed the kivy-package according to the official Kivy-page within conda. I tested whether this outside VSCode and started it in a terminal. This works:

But when I try the same environment within VSCode, I get this:

This is the animate.py example from kivy-examples.
import kivy
from kivy.animation import Animation
from kivy.app import App
from kivy.uix.button import Button
class TestApp(App):
def animate(self, instance):
animation = Animation(pos=(100, 100), t='out_bounce')
animation += Animation(pos=(200, 100), t='out_bounce')
animation &= Animation(size=(500, 500))
animation += Animation(size=(100, 50))
animation.start(instance)
def build(self):
button = Button(size_hint=(None, None), text='plop',
on_press=self.animate)
return button
if __name__ == '__main__':
TestApp().run()
So I expected it to work in vscode, but it does only work in a terminal. So my question: How to force VSCode to find and use SDL2?
Funnily, if I try the same thing as above with Kivy and Python2.7(!), it works in VSCode and terminal.

Answer 1

After playing around with VSCode and finding this helpful link, I finally changed:
1) user -> settings.json
"terminal.integrated.shell.windows": "C:\\WINDOWS\\System32\\cmd.exe",
2) if a workspace with different folders is used (as in my case) -> change ".code-workspace"
"folders": [
{
"name": "RASPIapp_py3",
"path": "C:\\Users\\<YOURPATH>\\RASPIapp_py3",
"python.pythonPath": "C:\\Users\\<YOURUSERNAME>\\Anaconda3\\envs\\<YOURENVNAME>\\python.exe",
"terminal.integrated.shellArgs.windows": [
"/K",
"C:\\Users\\<YOURUSERNAME>\\Anaconda3\\Scripts\\activate.bat",
"C:\\Users\\<YOURUSERNAME>\\Anaconda3"
]
}
No I just wonder why it was able to find kivy in the first place, even though it seems the only problem was that the conda-shell was not probabley activated.
