Description

Hi, I am trying to run the example code from the install Kivy. The following is the error I receive back. Any help would be great. I have tried looking at previous enquiries about similar problems, but nothing suggested on them has worked so far.

    def build(self):
        return Label(text='Hello world')

It looks like there's an issue with your sdl installation, can you try it without kivy.deps.sdl2? - import random
Are you getting this error when running the Kivy app via PyCharm IDE? - ikolim
To run it without 'kivy.deps.sdl2' the import error goes away, however I still get the error about being unable to find a window, abort. Yes this is trying to run it in PyCharm - Jaimie Dodd
Please refer to the solution at kivy-error-python-2-7-sdl2-import-error - ikolim

I had the same problem. I solved this by removing Kivy and its dependencies first.

python -m pip uninstall kivy

python -m pip uninstall kivy.deps.sdl2

python -m pip uninstall kivy.deps.glew

python -m pip uninstall kivy.deps.gstreamer

python -m pip uninstall image

Now reinstalling everything except gstreamer.

python -m pip install --upgrade pip wheel setuptools

python -m pip install docutils pygments pypiwin32 kivy.deps.sdl2 kivy.deps.glew --extra-index-url https://kivy.org/downloads/packages/simple/

python -m pip install kivy

It solved the error. Credits to Ben R's Answer.

I had the very same problem, and for me the solution was to make use of virtualenv instead of venv. This forces Kivy to use a specific installation of Python.

  1. Download and install Python 3.7, since 3.8 doesn't seem to be supported yet (https://www.python.org/downloads/release/python-376/)

  2. Install virtualenv if not already installed

    pip install virtualenv

  3. Create a virtual environment, specifying the path to the newly installed Python version

    virtualenv --python=C:\path\to\Python37\python.exe my_venv

  4. Activate the new virtual environment

    my_venv/Scripts/activate.bat

  5. Install kivy according to Javapocalypse's answer

    python -m pip install --upgrade pip wheel setuptools

python -m pip install docutils pygments pypiwin32 kivy.deps.sdl2 kivy.deps.glew extra-index-url https://kivy.org/downloads/packages/simple/

python -m pip install kivy

Sir please use venv I got the same error but I solves it using venv. Please create a virtualenv and install using your installation process. It works

I got the same problem with Python 3.9.1.

Reinstallation of kivy.deps.sdl2, kivy.deps.glew, kivy in the default user mode didn't work for me.

Then I found this comment, which suggested to install these packages in admin mode. It works. https://github.com/kivy/kivy/issues/5677#issuecomment-389990608

Keep your main file name main.py otherwise, it will raise this error. (Check this before doing anything).
