Kivy 1.11. 0 is the last release that supports Python 2. Now that python is installed, open the Command line and make sure python is available by typing python --version .
It's for Python 2 and You're On Python 3
and You want to downgrade for that!

How should I downgrade to Python 3.7 from Python 3.8? [duplicate]

This question already has answers here:
How to deal with Kivy installing error in Python 3.8?
(5 answers)
Closed 2 years ago.
I am trying to install kivy which does not support Python 3.8.
I have an app made on kivy on Windows 10. I am trying to build an apk. After following the instructions I figured I have Python 3.8 installed and always got an error when trying to install kivy on the VM LUbuntu.
I get this error when I try to install kivy using the sudo pip3 install kivy command.
raise DistutilsError(str(e))
distutils.errors.DistutilsError: Command '['/usr/bin/python3', '-m', 'pip', '--disable-pip-version-check', 'wheel', '--no-deps', '-w', '/tmp/tmpq9k_yp5j', '--quiet', '--find-links', 'https://github.com/kivy-garden/garden/archive/master.zip', 'cython!=0.27,!=0.27.2,<=0.29.10,>=0.24']' returned non-zero exit status 1.

How should I downgrade to Python 3.7?

Python 3.8: Try this
pip3 install kivy kivy_examples --pre --extra-index-url https://kivy.org/downloads/simple/

How about uninstalling Python 3.8 and then download the setup of Python 3.7 and install it.

How to deal with Kivy installing error in Python 3.8?

I have installed every necessary code in Python from Kivy, but the last one I need which one is python -m pip install kivy gets me an error like this:

This worked for me:

We are not likely to release a 1.11.1 version for 3.8 to pypi. However, you can install kivy master using:
pip install kivy[base] kivy_examples --pre --extra-index-url https://kivy.org/downloads/simple/

Try using pip install kivy==2.0.0rc2 or pip install kivy==2.0.0rc1
The command: pip install kivy==2.0.0rc2
Works with Windows 10 Pro and Python 3.8.3
And I test it with this code:
from kivy.app import App
from kivy.uix.button import Button
class TestApp(App):
def build(self):
return Button(text= " Hello Kivy World ")
TestApp().run()

This works in macOS Catalina 10.15.6 with python 3.8.0+
pip install kivy==2.0.0rc2

If you are using conda environment:
conda install -c conda-forge kivy
works in python 3.8

I am windows 10, with 3.8.2
seems pip install kivy==2.0.0rc2 worked. At least it installed.
time to tell if I can develop with it using 3.8.2
