Kivy window_sdl2 fails: "Unable to get a Window"

[nicolafiorello]

Hi! I am trying to get this project to work, but dependencies are pretty old and it's not that easy.

I am currently running Python 2.7.14, with these packages:

certifi==2021.10.8
chardet==4.0.0
Click==7.0
Cython==0.29.23
docutils==0.13.1
idna==2.10
Kivy==1.10.1
kivy-deps.glew==0.1.12
kivy-deps.gstreamer==0.1.17
kivy-deps.sdl2==0.1.22
Kivy-Garden==0.1.4
kivy.deps.angle==0.1.6
modbus-tk==1.1.2
Pillow==6.2.2
pygame==1.9.4
pyglet==1.2.4
Pygments==2.1.3
pymodbus==1.5.2
pypiwin32==223
pysdl2-dll==2.24.1
pyserial==3.2.1
pywin32==228
requests==2.12.4
six==1.11.0
urllib3==1.26.12

Now, with this python version I was able to get Kivy 1.10.1, which is needed because the project uses some functions deprecated in newest Kivy versions. But now I have a problem when I try to execute the script:

$ ./tools/launcher
./tools/launcher

Anyone can help? Any similar issue found online does not have a solution that fixes this. Thank you very much!
