[razed11]

Software Versions

• Python: 3.10.5
• OS: MacOS Big Sur 11.6.8 (Intel)
• Kivy: 2.1
• Kivy installation method: conda install -c conda-forge kivy

Describe the bug When running the "Hello World" example I get Unable to find any valuable Window provider. and it reports that it cannot load @rpath/libSDL2_image-2.0.0.dylib. More detailed logs below.

Expected behavior Display a window with "Hello world".

To Reproduce

#! /usr/bin/env python
import kivy

kivy.require("2.1.0")  # replace with your current kivy version !

from kivy.app import App
from kivy.uix.label import Label

class MyApp(App):
    def build(self):
        return Label(text="Hello world")

if __name__ == "__main__":
    MyApp().run()

Additional context Also tried with a Python 3.7 environment.

As a workaround, I linked the expected library to what exists and the example code worked.

cd /Users/Kenny/Anaconda3/envs/cryo/lib
ln -s libSDL2_image-2.0.601.1.0.dylib libSDL2_image-2.0.0.dylib

Hi Kivy team, I'm seeing exactly the same issue using:

• OS: Mac OS Monterey 12.6
• Python 3.8.13
• Kivy 2.1.0
• Kivy installation method: conda install -c conda-forge kivy

Error produced:

We are using Kivy in the Donkey Car project (https://github.com/autorope/donkeycar) and it prevents us from upgrading 2.0 -> 2.1. Could you please fix this in the package?

Cofirm, same here

[benpm]

• OS: macOS Monterey 12.6.5
• Python 3.8
• Kiv 2.1.0
• Installation: conda install -c conda-forge kivy

Same exact error.

As a workaround, I linked the expected library to what exists and the example code worked.

cd /Users/Kenny/Anaconda3/envs/cryo/lib
ln -s libSDL2_image-2.0.601.1.0.dylib libSDL2_image-2.0.0.dylib

This works, thank you. For me, Kivy was looking for "libSDL2_image-2.0.3.0.0.dylib" but the library in my Conda environment was "libSDL2_image-2.0.801.0.0.dylib".

To resolve:

1. Navigate to /Users/{user}/opt/anaconda3/envs/{env_name}/lib
2. Create a copy of the "libSDL2_image-2.0.{x}.0.0.dylib" file
3. Change the name of the copy to "libSDL2_image-2.0.3.0.0.dylib" OR whatever the name of the library is in the ImportError you get when trying to run your program with python3 -d your_program.py.
